Description
Technical field:
The utility model relates to a kind of immunochromatography combined detection cards.
Background technique:
Lateral flow detection method is also referred to as lateral flow immunochromatographic measurement, is for target analytes in test sample
The portable unit that whether there is, can use, can be equipped with small and exquisite in the case where not needing special and expensive equipment
Portable detection device is as support;Under normal conditions, these reagent facilities are used for the medicine of home test, emergency treatment or laboratory
Diagnosis;One wide-scale distribution and well-known application example the most is home-use pregnancy test card.
Sample pad in immunochromatography plays the role of sponge, contains excessive sample liquids;Once being saturated, liquid
Flowing transport is into labeling pad, the marker that store in labeling pad, is dry biologically active granulated
Formula, keeps activity in the matrix such as salt and sugar, and with detected target molecule specificity can occur for these active materials
Reaction, as the compound of the immune combination of antibody antigen, these reactions has been fixed at the surface of the particles.When sample liquids dissolve
When salt saccharide matrix, it can also dissolve in particle wherein, and while flowing through porous structure film, and be fixed in the above in advance
Other ligand binding, the band being formed on fixed position, there are two types of band is general, test strip shows detected target
The content situation of object, whether Quality Control band represents flowing reactive state good.Final liquid, which flows into, to be absorbed in phase, test
It completes.
C reactive protein is typical acute phase protein in inflammatory reaction;It is synthesized by liver and by five identical polypeptide chain
Composition forms the five-membered ring that molecular weight is 105000 dalton;CRP be it is most sensitive in acute phase reactant, in inflammation mistake
Its concentration increases sharply in journey;Compound CRP activates the complement system started with C1q；Then the conditioning of CRP starting invasion cell is made
With and phagocytosis, but its major function be combine and detoxify by tissue damage generate endogenous noxious material；CRP detection is used
In detection systemic inflammatory process；Assessment antibiotic treatment bacterium infection；It is broken with early stage amnion simultaneously to detect intrauterine infection
It splits；Distinguish the disease of the active and inactive form of infection simultaneously, for example, in the patient for suffering from SLE or ulcerative colitis into
Row；It therapeutically monitors rheumatic disease and assesses anti-inflammatory therapy；It determines that there are postoperative complications in early stage, such as infects
Wound, thrombosis and pneumonia, and distinguish infection and marrow graft rejection reaction；High quick CRP test has been used for early detection
Pediatrics and coronary heart disease risk assessment.Some researchs are concluded that highly sensitive CRP detection may be used as pre- detect
The index of aobvious healthy population coronary heart disease risk, and the index as prediction recurrent events；The increase of CRP value be it is nonspecific,
It should not be explained in the case where no complete clinical medical history.
Interleukin-6 (IL-6) is the pleiotropic cytokines with wide variety of functions；It is described as interfering first
Element-β 2, plasmacytoma growth factor and hepatocyte-stimulating factor；It is described as human B cell stimulating factor 2(BSF2 later).?
1988, it is thus proposed that IL-6 is named as, because further the verified protein of research not only shows B cell
Activity, and show T cell, candidate stem cell, the activity of liver cell and brain cell；One coding, 212 amino acid products
Term single gene is generated the peptide of 184 amino acid of the molecular weight between 22-27 kDa in the end N- by cutting.1989,
It is reported that the immunocompetence compound there are also some 60-70kDa is detected in the body fluid of acute bacterial infection patient；With
Damage, wound, pressure, infection, brain death, tumor are formed during acute inflammatory reaction relevant with other situations, and IL-6 is fast
Speed induction generates；The IL-6 concentration of detection trauma patient can predict the late complication of more Fundamental Operations, or instruction
It fails to pinpoint a disease in diagnosis or complication；The continuous measurement of IL-6 in the serum or blood plasma of the patient of ICU is moved in, display can be used for assessing SIRS(complete
Body inflammatory response syndrome), the severity of pyemia and infectious shock, and predict the prognosis of these patients；IL-6 can also
As Early warning indicator for detecting sepsis of the newborn；IL-6 also works in chronic inflammation, such as rheumatoid arthrosis
It is scorching.
The prohormone that Procalcitonin (PCT) is made of 116 amino acid, molecular weight are about 12.7 kD；PCT is by mind
Through endocrine cell (the C cell including thyroid gland, lung and pancreatic tissue) express, through digestion be decomposed into (prematurity) calcitonin,
C-terminal peptides and amino terminal peptide.Only contain a small amount of PCT in Healthy People blood；It has been found that PCT can be significantly raised after bacterium infection.It is dynamic
When object model test shows that septicopyemia occurs for body, Various Tissues may express PCT；The intracorporal PCT of patients with sepsis
114 amino acid are contained only, the Ala-Pro of amino terminal is lacked；The raising of PCT level sees bacillary septicopyemia, especially
Severe septicopyemia and infectious shock；PCT can be used as the prognostic indicator of patients with sepsis；It is also acute critical pancreatitis
And its reliability index of major complications；For Community Acquired Respiratory Tract Infection and air-conditioning inductivity patients with pneumonia, PCT can make
For the index of antibiotic selection and curative effect judgement.
Serum amyloid A protein (SAA) protein includes (12-14kDa, the 104-112 amino acid of a small-molecular-weight
Residue) family is the protein of highly conserved differential expression in vertebrate；SAA albumen participates in acute phase response；This
A little reactions are the direct host responses for early stage being directed to inflammation；In acute stage, recycles SAA level and increase 100-1000 times, concentration
Reach 1 milligram every milliliter；SAA further relates to several morbid states, including rheumatoid arthritis, atherosclerosis, AA starch
Sample denaturation and coronary artery disease；Liver is the main portions of SAA synthesis, expresses outside liver and also has been reported that；Mankind's SAA gene family
It is positioned at No. 11 chromosomes；In human body, identified four kinds of SAA genes and three kinds of protein products: mankind SAA1 and
SAA2 is designated as acute stage SAA(A-SAA) isotype；And SAA4 is composition expression type, and SAA3 is pseudogene；A-SAA
Belong to a kind of acute phase protein, further includes C reactive protein (CRP), haptoglobin, ceruloplasmin, complement in this type
Ingredient C3 and C4, α 1- acidoglycoprotein, Prolastin and fibrinogen.In human body, CRP and SAA be all
Acute stage synthesis；And in mouse, SAA is main acute phase protein.
As the albumen of inflammatory reaction acute stage, C reactive protein, Procalcitonin, interleukin-6, serum amyloid sample
Albumin A has important auxiliary diagnosis meaning early stage infection and in the development process of inflammation；Meanwhile in Other diseases state
In, also marker also will appear measurable apparent increase for this；Therefore, the joint-detection of these markers is very significant
's；There is presently no reagents can detect these four markers simultaneously, clinically needs to separate progress, or even need using different
Detection method reagent carry out, if Procalcitonin, interleukin-6 use immunochromatography or chemiluminescent method, together
When C reactive protein, serum amyloid A protein detected using the method for immunoturbidimetry.Even same detection method,
The detection of these four markers also largely needs separately to carry out, or needs the cooperation of the fully-automatic equipment of higher cost.
