ELISA Kit features: Comprehensive Quality Assurance

Sino Biological Inc. ELISA Kits are complete and ready-to-use. Immunoassays are available for measuring a range of molecules including virus, cytokines, interleukin, chemokines, growth factors, CD molecule and more. The features of the ELISA Kit are easy to use, high sensitivity, high repeatability.

The high sensitivity of ELISA, comes from the enzyme as a reporting group. As is known to all, the enzyme is an organic catalyst, a small amount of which could induce a large span of catalytic reactions to produce observable chromogenic reaction phenomenon. Therefore, this system is often taken as the amplification system of enzyme. By ELISA, a tracer of the antigen or antibody is achieved in the cell or subcellular level, also, antigen or antibody quantification can be done in the microgram or even nanogram levels.

Specificity of ELISA is because of the selectivity of the antibody or antigen. Actually, the binding of antigen or antibody only occurs in the epitope of an antigen or antigen-binding site of an antibody. Since, there is a complementary relationship between epitope and antigen-binding site both in chemical structure and spatial configuration, the reaction between antigen and antibody shows a strong specifity.

linearity range

Through the linear range, we can calculate the actual testing sample value.

Limit of detection

The limit of detection is the test index of sensitivity , the lower detection limit, the higher the sensitivity.


Precision is the test index of repeatability,the higher precision, the better the repeatability.


Linearity is the test index of experimental accuraty and specificity.


Recovery is the test index of experimental accuraty and specificity.


The better the Stability,the longer expiration date.

Interfering test

Interfering test can confirm that whether the kit is specific for detecting.

Cross reaction

Cross reaction can also confirm that whether the kit is specific for detecting.

Natural samples Detection

The natural samples could be detected,and the sample valuse can be as the reference for the user.
