Description

The ELISA kit of validity can be detected fast

Technical field

The utility model relates to technical field of immunological detection, specifically a kind of ELISA kit that can detect validity fast.

Background technology

Kit manufacturing enterprise all faces an important problem in process after sale, it is exactly kit problem after sale, kit inefficacy is main refers to that the standard items inside standard items bottle lost efficacy, the inefficacy of kit, also may be relevant with experimenter's using method with kit transport, kit preservation condition except the problem of the stability of product own.Due to the use problem of kit, kit manufacturer its after sale in all to drop into a large amount of manpower and materials and go to address this problem, because manufacturer and experimenter are difficult to persuade the other side, the product that often user self does not have proper use of kit to cause after sale often also is attributed to the product quality problem of kit manufacturer.Therefore, need one under kit unused state, just can offer an explanation the whether effective way of ELISA kit fast.

Summary of the invention

The purpose of this utility model is to solve the problems of the technologies described above, provide a kind of structure simple, easy and simple to handle, can just can easily learn whether kit lost efficacy and can detect the ELISA kit of validity fast before kit Kaifeng or before standard items use.

Technical scheme comprises the standard items bottle in box body and box body, containing biologically active indicator in standard items in described standard items bottle, the slot being fitted with standard items bottle is provided with in described box body, described box body has the colorimetric window be communicated with slot, the box body outer wall that described colorimetric window is other posts standard items colorimetric card.

Described standard jar body also posts standard items colorimetric card.

Biologically active indicator is activated protein bright in colour, as DsRed, green fluorescent protein etc., in standard items, add colored activated protein make standard items also with color, these albumen only could produce color in activated situation, if structural change or degraded all can make color thin out; According to parallel presumption, if colored activity of active protein lowers, so the activity of standard items also can correspondingly decline certainly, when the standard items color and luster containing biologically active indicator subtracts to a certain extent light, carry out color comparison by the standard items colorimetric card made in advance, just can judge whether kit can continue to use.

Based on the improvement of above-mentioned determination methods, standard items colorimetric card is attached on the outer wall of kit, and on box body, open colorimetric window, make to be inserted in slot internal standard product body (liquid level is with lower part) in box body to be exposed by colorimetric window, because standard items bottle is clear vial, therefore the color change of standard items is also learnt by the range estimation of colorimetric window.Like this, even if kit is in non-opening status, operator sees the change of standard items bottle internal standard product color by colorimetric window, and energy is direct and the other standard items colorimetric card of colorimetric window carries out color contrast, to judge that whether kit is effective fast.Because this decision method can carry out at kit unused state, thus clearly can offer an explanation the reason of kit inefficacy, be namely the problem judged due to the stability of product own or transport, or operator self using method problem.If kit just by finding after the comparison of standard items colorimetric card that the color change of standard items meets the standard of inefficacy when unused state, then can be known and learn and to have nothing to do with operator self using method.

Further, in order to improve the reliability of judgement, standard jar body also posts standard items colorimetric card, so as by after taking out standard jar in box body, use the range estimation criterion product that take a step forward whether effectively genuine or lost efficacy.

Because the manufacture of colorimetric card is relevant with the concentration adding biological indicator in standard items, therefore standard items colorimetric card should preferably be manufactured by manufacturer, same series-produced kit uses corresponding standard items colorimetric card, and is directly affixed on box body and/or bottle, is convenient to unification and compares and judge.

The utility model structure is simple, easy and simple to handle, under kit unused state, can judge that whether kit is effective fast.

Accompanying drawing explanation

Fig. 1 is the structural representation (only depict standard items bottle and slot thereof, other accessory and corresponding slot omit) of the utility model kit.

Fig. 2 is the front view of standard items bottle.

Wherein, 1-box body, 2-slot, 3-standard items bottle, 4-colorimetric window, 5-standard items colorimetric card.

Embodiment

Below in conjunction with accompanying drawing, explanation is further explained to the utility model:

With reference to Fig. 1, be fitted with standard items bottle 3 in the slot 2 of kit 1 (experimentally to need also can be fitted with other accessory in box body 1 as ELISA Plate, standard QC, antibody pipe, Washing liquid bottle, dilution bottle and substrate bottle etc., this is prior art, do not illustrate in the drawings), containing biological indicator (as DsRed) in the standard items in described standard items bottle 3.The slot 2 being fitted with standard items bottle 3 is provided with in described box body 1, described box body 1 has the colorimetric window 4 be communicated with slot 2, described colorimetric window 4 is corresponding with the part below standard items bottle 4 liquid level, and box body 1 outer wall that described colorimetric window 4 is other posts standard items colorimetric card 5.Part more than described standard items bottle 4 body liquid level also posts standard items colorimetric card 5.

The manufacture of colorimetric card:

Biologically active indicator (DsRed) is added in standard items in standard items bottle 3, concentration is 1mg/ml, the lattice that when dispatching from the factory, the color of standard items is the darkest with standard items colorimetric card 5 (having by being deep to shallow three lattice colors) color are identical, are designated as effectively.

Before operating personnel do not break a seal to kit, the color of the standard items bottle 4 Plays product exposed by colorimetric window 4 is estimated by colorimetric window 4, if with first lattice (the most dark) of color and standard items colorimetric card 5 or the second lattice same or similar with being judged to effectively, can normally use; Or color is identical with the 3rd lattice (the lightest) or be shallower than the 3rd lattice, then judge that kit lost efficacy.Further, before opening kit use standard items bottle 3, also can with further reference to the color of the standard items colorimetric card 5 comparison standard items bottle 4 Plays product on body, determination methods is the same.

Claims (2)

1. one kind can be detected the ELISA kit of validity fast, comprise the standard items bottle in box body and box body, it is characterized in that, containing biologically active indicator in standard items in described standard items bottle, the slot being fitted with standard items bottle is provided with in described box body, described box body has the colorimetric window be communicated with slot, the box body outer wall that described colorimetric window is other posts standard items colorimetric card.

2. can detect the ELISA kit of validity as claimed in claim 1 fast, it is characterized in that, described standard jar body also posts standard mouth colorimetric card.
