Enzyme-linked immunosorbent assay (ELISA), also known as an enzyme immunoassay (EIA), is a biochemical technique used mainly in immunology to detect the presence of an antibody or an antigen in a sample. The ELISA has been used as a diagnostic tool in medicine and plant pathology, as well as a quality-control check in various industries,such as ELISA application in food industry. In simple terms, in ELISA, an unknown amount of antigen is affixed to a surface, and then a specific antibody is applied over the surface so that it can bind to the antigen. This antibody is linked to an enzyme, and in the final step a substance is added that the enzyme can convert to some detectable signal, most commonly a colour change in a chemical substrate.
Sino Biological Inc. provide more than 6000 ELISA antibodies for different species, and the species are include ferret, canine, cynomolgus, virus and more.
Sino Biological Inc. is the largest independent producer of recombinant proteins. The proteins are more than 90% purity, and are proved good bioactivities.
Sino Biological Inc. provide more than 6000 ELISA antibodies for scientific study, and the antibodies would be validated by cross-reactivity, which can prove the antibodies are specific or not.
Sino Biological Inc. ELISA antibodies are tested by recombinant protein with low coating concentration, and which could ensure the sensitivity of antibodie.
