Description of the Invention: [Technical Field to Which the Invention Is Applicable] The present invention relates to a detection test of a kind of New Zealand>1', particularly a test for quantitative detection of κ. [Prior Art] In the conventional technique of quantification of biological specimens, it is often used to take a specific measurement of the specificity of the immune molecule. For example, the transmission of the limbs is carried out (enzyme touch ^ ❹ imm dish 〇 1 - sleeve As; ELISA) 'More in 96-well plates (96_wdl, and by the signal from the side of the final enzyme reaction, push back the concentration of the substance to be tested. But because of this test 'to avoid immune molecules and analytes In order to non-specifically combine other impurities involved, it is necessary to add a cleaning step at each reaction stage, and the reaction reagent that is not combined with the product or other immune molecules is removed from the 96-well plate to avoid excessive enzyme retention. The false positive signal caused by each well (well) leads to the test failure. Due to the development of electromechanical technology, the test strips with micro flow channel structure have been used for immunosampering 'simplified the above traditional test methods After the step, the complicated process such as cleaning is carried out. However, it is known that the test piece needs to be added to the reagent or the substrate required for the reaction. Adding to the test piece. The reaction reagent or the substrate is separated from the test piece. 'The method of adding the lion to the lion is 75. It is the reaction of the sputum or the f, and it cannot be stored for a long time at room temperature. It needs to be stored in a specific environment (such as refrigerated_light preservation) to avoid test errors caused by deterioration of the reactants. Therefore, such test strips are still inconvenient in operation and storage. The fluid detection test of the flow channel structure is because the fluid around the flow channel is not a water-absorbent material, and the fluid is mostly composed of a highly viscous composition such as a protein or an enzyme, so that when the fluid to be tested flows, it will be on the flow path. Residual, the fluid to be tested cannot be completely reacted, which not only causes waste of the fluid to be tested, but is more likely to cause errors in the final test results. 3 201017160 In addition, the fluid detection test piece with micro flow path structure is known to be in fluid transfer. In one aspect, the capillary phenomenon generated by the microchannel structure is used to passively transfer the fluid to the reaction detection region through the flow channel; the other method is to use the pressurized method when injecting the fluid to be tested. The fluid is given a driving force so that the fluid can actively pass through the flow passage to reach the reaction detecting region. However, in any of the above manners, the fluid to be tested is often injected into the flow passage to generate bubbles of different sizes, causing the flow passage to block, resulting in actual The error in measurement 'even causes the test to fail. SUMMARY OF THE INVENTION To overcome the above disadvantages, the present invention provides a fluid detecting test piece comprising a ginseng plate having a flow path. The flow path is provided with a first fluid region sequentially connected a second fluid zone and a third fluid zone, wherein the first fluid zone is for fluid injection. Further, the flow channel has a first antibody, a domain material, a peroxide ruthenium, a second antibody, a luminescent agent, and a host reaction. The first antibody is located in the first fluid zone for identifying the substance to be tested, and the saccharide material and the peroxide are located in the first fluid zone or the second fluid zone. The second antibody is immobilized (immobHize in the second fluid region, and also identifies the same substance to be tested, and the second antibody and the first antibody system recognize different antigen-determining positions (epit〇p0. Luminescent agent and receptor) The reaction reagent system is located in the third flow ship, and the host reaction reagent contains saccharide ruthenium oxide. Thereby, after the fluid containing the substance to be tested is injected into the flow channel, the first antibody, the listening material and the gasified sputum As the fluid flows, part of the peroxide is combined with the first antibody, the test substance and the second antibody, and is placed on the second reading, and the unmixed misty flow to the first a three-fluid zone, and the sugar-oxidized plum catalyzes the oxidation of the auditory material flowing to the third fluid zone, and produces hydrogen peroxide (2), and the luminescent agent is subjected to peroxide flowing to the third fluid zone. Mei catalysis reacts with peroxidic wind and produces an optical signal. Therefore, the main object of the present invention is to provide a fluid test strip, which has no reagents and materials required for all reactions. Direct and quantitative final response signal Quantitative detection. Another object of the present invention is to provide a kind of side test piece, and the reagent and material of the towel reaction are stored in the test #t, so it can be stored for a long time without causing reagents. Change 4 201017160 quality and lead to test error.

流體檢測試片1包含有基板1〇,基板1〇包含有流道1卜流道U上設置有 依序連接之第-流體區、第二流體區112與第三流趙區113,其中第一 流體區111係供流體之注入。 請繼續參考第1B圖,為本發明第—較佳實施例流體檢測試片流道中反 應材料分佈示意圖。第-流體區m中具有第一抗體冊、聽類材料1112 及過氧化物騰1113。第二流體區112中具有第二抗體U21,而第二抗體1121 疋固定在第二流體區112之中。又,第一抗體im與第二抗體1121都是辨 識流體中的同一麟測物質臟,但是第-抗艎1111與第二抗體1121是各 ® 自辨識待測物質1101上不同的抗原決定位置。所以在第一抗體1111和第二 抗體1121的選用上,兩者均可為單株抗體(mAb》或多株抗體(pAb),只 需要第一抗體1111和第二抗體1121是一組抗體配對(antib〇dy pair),在進 行抗原辨識時,不致發生互相干擾的狀況即可。第三流體區113之中則具有 發光劑1131與受質反應試劑1132,受質反應試劑1132包含有醣氧化臃 1133 °其中’過氧化物酶m3可以是辣根過氧化物酶(HRp, H〇rseradish Peroxidase)、抗壞血酸過氧化物腾(AP,Ascorbate Peroxidase)或是過氧化氫腌 (hydrogen peroxidase)。在較佳的實施狀態中,發光劑1131是用3_氨基鄰苯 ❷ 二甲醯肼(5-Amino-2,3-dihydro-l,4-phthalazinec!ione),而醣類材料 1112 則可 為葡萄糖’於此同時,醣氧化臃1133則是選用葡萄糖氧化臃。 請繼續參考第1C至第1E圖,為本發明第一較佳實施例流體檢測試片 流道中反應材料在不同反應階段的分佈示意圖。首先請參考第1C圖,當含 有待測物質1101的流體注入流道11之後,第一抗體1111會辨識到待測物 質1101,並與其做結合。此外,由於第一抗趙1111、酷類材料1112及過氧 化物晦1113並未固定於第一流體區中,所以此時第一抗體lm、與第一抗 體1111結合之待測物質1101、過氧化物臃1113,及醣類材料1112會隨著流 6 201017160 體一起繼續往第二流體區112流動。 請繼續參考第1D圖,當流體流至第二反應區112之後,第二抗體1121 會與待測物質1101結合。此時,由於第二抗體1121是固定在第二流體區112 之中,所以會將已經與待測物質1101結合的第一抗體mi以及在第一抗體 1111之上的過氧化物晦1113—併留置於第二流體區112之中;而此時亦流 至第二流體區112的醣類材料m2則會和未與待測物質11〇1結合的第一抗

化氫以及發光劑1131會受到流至第三反應區113的過氧化物腌1113進行催 化,產生光學訊號。此時,可藉由偵測光學訊號的強度,推算出參與反應的 酵素濃度,亦即可藉由偵測光學訊號的強度推算出有多少過氧化物梅1113 流至第二流體區113 ’且由於在製作流體檢測試片1之時,要添加的過氧化 物腌1113含量係為一已知的固定值,所以留置於第二流體區112之中的過 氧化物晦1113其濃度亦可藉由兩者簡單相減後推算得知。最後,利用已知 Ο 的留置於第二流體區I12之中的過氧化物腌1113的濃度,可再推算出流體 中所含有的待測物質1101的濃度,以達到定量檢測的目的。 在未反應則,第一抗體1111與過氧化物腾1113兩者的結合型態可以是 直接形成共軛結合(conjugation);或是第一抗體1111上共軛結合有生物素 (Biotin),而過氧化物晦1Π3則與親和素(Avidin)共輛結合,利用生物素 與親和素會強力結合成一錯合物(AB complex)的特性,使得在進行反應時, 當有第一抗體1111留置於第二流體區112時,也會將部份的過氧化物晦1113 固定留置於第二流體區112。上述之親合素可以是卵白素(Avidin)、鏈黴親 合素(Streptavidin) ’或是中性鏈親和素(NeutrAvidin)。

The fluid detecting test piece 1 includes a substrate 1 〇, and the substrate 1 〇 includes a flow path 1 on which a first fluid region, a second fluid region 112, and a third fluid region 113 are sequentially disposed. A fluid zone 111 is for fluid injection. Please refer to FIG. 1B for a schematic diagram of the distribution of the reaction material in the flow path of the fluid detecting test piece according to the first preferred embodiment of the present invention. The first fluid region m has a first antibody book, a listening material 1112, and a peroxide 1113. The second fluid region 112 has a second antibody U21 therein, and the second antibody 1121 is fixed in the second fluid region 112. Further, both the first antibody im and the second antibody 1121 are identifiable to the same cytoplasm in the fluid, but the first anti-sputum 1111 and the second antibody 1121 are different antigen-determining positions on the respective self-identifying test substance 1101. Therefore, in the selection of the first antibody 1111 and the second antibody 1121, both of them can be monoclonal antibodies (mAbs) or multiple antibodies (pAbs), and only the first antibody 1111 and the second antibody 1121 are a pair of antibody pairs. (antib〇dy pair), in the case of antigen recognition, there is no possibility of mutual interference. The third fluid region 113 has a luminescent agent 1131 and a substrate reaction reagent 1132, and the receptor reaction reagent 1132 contains glucose oxidation.臃1133 ° where 'peroxidase m3 can be horseradish peroxidase (HRp, H〇rseradish Peroxidase), ascorbate peroxidase (AP), or hydrogen peroxidase. In a preferred embodiment, the illuminant 1131 is 3-amino-2-pyrazine (5-Amino-2,3-dihydro-l, 4-phthalazinec!ione), and the saccharide material 1112 is At the same time, glucose oxidized cesium 1133 is selected from glucose cerium oxide. Please continue to refer to Figures 1C to 1E for the distribution of the reaction materials in the flow path of the fluid detecting test strip in the first preferred embodiment of the present invention. Schematic. Please refer to the 1C first. After the fluid containing the substance to be tested 1101 is injected into the flow channel 11, the first antibody 1111 recognizes and combines with the substance to be tested 1101. In addition, since the first anti-Zhao 1111, the cool material 1112 and the peroxide 晦1113 is not fixed in the first fluid region, so at this time, the first antibody lm, the test substance 1101 combined with the first antibody 1111, the peroxide 臃1113, and the saccharide material 1112 will follow the flow 6 201017160 Continue to flow to the second fluid zone 112. Please continue to refer to Figure 1D, after the fluid flows to the second reaction zone 112, the second antibody 1121 will bind to the test substance 1101. At this time, since the second antibody 1121 is fixed at In the second fluid region 112, the first antibody mi that has been bound to the substance to be tested 1101 and the peroxide 晦 1113 above the first antibody 1111 are left in the second fluid region 112; The saccharide material m2 which also flows to the second fluid region 112 at this time and the first antibody 1111 and the peroxide plum 1113 which are not combined with the substance to be tested 11〇1 continue to the third fluid region 113 as the fluid continues. Flow. Please continue to refer to Figure 1E, sugar materials M2 and the peroxide 臃1113 which is not retained in the second fluid region 112 in combination with the first antibody lm, the second antibody ©1112, and the test substance 1101, will flow to the second fluid region 113. At this time, the saccharide material M2 will be oxidized with the sugar oxidized plum 1133 already present in the third stream Zhao 113 to produce hydrogen peroxide, and the generated hydrogen peroxide and the illuminant 1131 will be flowed to the third reaction zone 113. The peroxide salted 1113 is catalyzed to produce an optical signal. At this time, by measuring the intensity of the optical signal, the concentration of the enzyme involved in the reaction can be estimated, and by detecting the intensity of the optical signal, it is estimated how much peroxide plum 1113 flows to the second fluid region 113' and Since the peroxide 1113 content to be added is a known fixed value at the time of preparation of the fluid test strip 1, the concentration of the peroxide 晦 1113 remaining in the second fluid region 112 can also be borrowed. It is estimated by simple subtraction between the two. Finally, the concentration of the test substance 1101 contained in the fluid can be further calculated by using the concentration of the peroxide salt 1113 remaining in the second fluid region I12, which is known to be Ο, for the purpose of quantitative detection. In the case of unreacted, the binding form of the first antibody 1111 and the peroxide 1113 may be direct formation of conjugation; or the first antibody 1111 is conjugated to biotin (Biotin). The peroxide 晦1Π3 is combined with avidin (Avidin), and biotin and avidin are strongly combined to form a complex of AB complex, so that when the reaction is carried out, when the first antibody 1111 is left In the second fluid zone 112, a portion of the peroxide crucible 1113 is also retained in the second fluid zone 112.

Process 'simultaneous nitrification _ dissolution The second ship fiber layer and the second antibody 1121 are formed to remain in a powder form. Further, the manner in which the substrate reaction reagent 1132 is formed in the third nitrocellulose layer 113 is also formed in the second nitrification with the second antibody 1121. The manner of the fiber layer 112〇 is roughly as follows, and the third fiber layer can be formed first and then injected by the f-reaction test ship, or mixed with the nitrocellulose solution, and then injected into the bottom of the third fluid zone 113. There are two ways, so I won't repeat them here. In addition to the above-described first-preferred embodiment, the present invention also provides a method for detecting the second method, the following second preferred real towel ride, and the towel is checked. The structure of the cap system is substantially the same as that of the first preferred embodiment, so the description of the test piece component mentioned in the above is not repeated, and reference is made to the first to the first. Referring to Fig. 2, there is shown a flow chart of a fluid detecting method according to a second preferred embodiment of the present invention. The fluid detecting method 2 comprises the following steps: Step 21 'Long 1 for a fluid' fluid containing the substance to be tested 1101, please refer to paragraph 1 Fig. Step 22.

The third fluid zone 113 has a hair spray 11S1 and a substrate reaction reaction (1) 2, and the host reaction reaction 1132 contains a brewing oxygen 201017160. Among them, the peroxide gland m3 may be horseradish peroxide strontium, ascorbic acid peroxide salt or hydrogen peroxide plum. In a preferred embodiment, the luminescent agent 1131 is 3-aminophthalic acid, and the saccharide material 1112 is glucose. At the same time, the sugar oxidizing 1133 is glucose oxidized plum. In addition, various distributions of the saccharide material 1112 and the peroxide 晦1113 in the flow channel 11 are as described in the first preferred embodiment (please refer to FIG. 1B, FIG. 1F, FIG. 1G, and FIG. 1H). ). Step 23: Add fluid to the first fluid zone m of the flow path u. The fluid flows along the flow path u sequentially from the first fluid region 111 through the second fluid region 112 to the third fluid region 113, and the first antibody Π11, the saccharide material 1112 present in the flow channel 11 And peroxidase 1113 follows the fluid flow.

In the third fluid zone, the saccharide material 1112 is oxidized by the oxidation of the sugar oxidase 1133, and the hydrazine hydrogen peroxide is generated, and the fine electrode 1131 is catalyzed by the peroxide 晦 1113 flowing to the third fluid region 113. Hydrogen peroxide reacts and produces an optical signal. Step 25: When the optical domain μ generated by the step 24 is fine, the intensity of the side optical signal can be 'transferred out of the enzyme concentration participating in the reaction', and the amount of the peroxide plum can be estimated by detecting the intensity of the optical signal. 11B flows to the third fluid zone (1)' and since the content of the peroxide 晦 1113 to be added at the time of the preparation of the fluid test strip 1 is a known fixed value, it is left in the first fluid region m. The concentration of peroxidation _ 1113 can also be estimated by simply subtracting the two.
