Abstract

The utility model relates to an enzyme labeled plate with adsorptive force, which is characterized in that the rugged inner surface of a sample cup in the enzyme labeled plate is processed into an irregular granular shape or processed into the shape of a circular arc or a rectangle or an axial shape of a triangle or a spiral shape or an annular shape. The area of the inner surface of the sample cup is enlarged, the adsorbing quantity of samples needing to be measured is increased in order to enhance the sensitivity of the enzyme labeled plate and the concentration and the dosage of packed samples are relatively reduced.

Description

ELISA Plate with absorption affinity

Technical field

The utility model relates to a kind of ELISA Plate, particularly relates to the ELISA Plate that a kind of inwall has absorption affinity.

Background technology

ELISA Plate (ELISAPLATE) be enzyme linked immunosorbent assay (Enzyme LinkedImmuno-sorbent Assay, ELISA) in important carrier instrument.It has important effect in immunological response.The purity of the antigen of immunological response, antibody, labelled antibody or antigen, concentration and ratio, damping fluid kind, concentration and ionic strength, pH value and conditions such as temperature of reaction, time are all in close relations with ELISA Plate.In addition, surperficial absorption to antigen, antibody or antigen antibody complex also plays an important role as the solid phase material polystyrene (Polystyrene) of carrier.Antigen, antibody and other biomolecule are adsorbed to carrier surface by number of mechanisms.

The ELISA Plate that is used for the immunoassay experiment is the structure of a kind of inside surface without any processing, and the adsorbed sample (being commonly referred to the bag quilt) in the sample cup in this kind of enzyme target (being commonly referred to microwell plate in this area) surface is generally 0.1～0.125ml as the adsorbance (or amount of title envelope antigen, antibody or mark) to antigen, antibody or mark.Because the restriction of inside surface surface area makes that the amount of reactant absorption is very limited.In immunoassay experiment, because that the absorption quantitative limitation causes some immunoreactive susceptibility is lower.Formerly immune response is tested the not high phenomenon of susceptibility that place often runs at each in the technology, and one of its important reasons is exactly to come from the lower problem of the adsorbance of sample cup in the ELISA Plate.

Summary of the invention

The purpose of this utility model is to make physics on the inside surface in the sample cup in ELISA Plate to handle (except the bottom), and it is uneven that inside surface is presented, and is processed into the shape of solid geometry, thereby the surface area of inside surface is increased.By increasing the surface area of sample cup bag quilt in the ELISA Plate, make the increase of the encrusting substance of absorption, thereby improve the susceptibility of ELISA Plate.

To achieve the above object, the technical measures taked of the utility model are: the surface area that increases the sample cup inside surface.Promptly comprise housing, be divided in housing empty every elastic baffle and central dividing plate and place emptyly every interior sample cup, make the inside surface of sample cup become rough.

Benefit of the present utility model is significant.For onesize sample cup, the utility model obviously is the surface area that has increased inside surface because inside surface is rough.When filling with sample in the sample cup, the amount of the sample that the sample of big surface area absorption is more adsorbed than little surface area is big.The amount of absorption (or claiming package amount) is big more, and the susceptibility of measurement is just strong more.And can relatively reduce the concentration and the consumption of sample.

For advantage of the present utility model more clearly is described, be that example illustrates only with hepatitis b virus s antigen diagnostic kit common in the immune response.Each 10 example of hepatitis b virus s antigen feminine gender, the positive and quality controlled serum sample of choosing respectively under the similarity condition experimentize, and draw following result.Represent with table one, two:

Table one: (in the table: ELISA Plate of the present utility model is called the S plate, and formerly the ELISA Plate of technology is called the N plate, embodiment n=10 example)

The ELISA Plate type	The negative average OD value of sample (absorbance)	The average OD value of positive sample (absorbance)
The ELISA Plate type	The negative average OD value of sample (absorbance)	The average OD value of positive sample (absorbance)	The S plate	＜0.020	2.95
The N plate	＜0.020	2.50	The S plate	＜0.020	2.95

Table two: the quality controlled serum sample with variable concentrations experimentizes, and test S plate and the average OD value (embodiment n=10 example) of N plate under similarity condition draw following result:

The ELISA Plate type	4ng/ml OD value (absorbance)	2ng/ml OD value (absorbance)	Ing/ml OD value (absorbance)	0.5ng/ml OD value (absorbance)
The ELISA Plate type	4ng/ml OD value (absorbance)	2ng/ml OD value (absorbance)	Ing/ml OD value (absorbance)	0.5ng/ml OD value (absorbance)	The S plate	1.8	0.95	0.42	0.20
The N plate	1.5	0.77	0.35	0.15	The S plate	1.8	0.95	0.42	0.20

Test result shows: the testing result to identical sensitivity quality controlled serum shows: all greater than the mean light absorbency of N plate, in immune response was analyzed, such result was considered as susceptibility and improves the mean light absorbency of S plate.The susceptibility ratio of the utility model S plate formerly N plate of technology has improved 20.0～33.3%.
