Immuno Diagnostics


BioChain has developed a series of ELISA assays for the detection of infectious diseases, such as hepatitis, (HCV, HEV), HIV, TORCH, TB, etc. Our kits are for research use only in the United States while we have obtained regulatory approval for clinical use in other countries, such as China. These ELISA kits are enzyme immunoassays for the detection of various antigen or antibody in human serum or plasma. Recombinant, purified antigen, or antibody is coated on the multiple wells. When the serum sample and HRP conjugated second antibody are added to the coated wells and the target antibody or antigen is present in the sample, a HRP conjugated complex will form. This enzyme reaction produces a color change, and the intensity of the absorbance at defined wavelength indicates the presence or absence of the antigen or antibody in the sample. The test is specific, sensitive, reproducible and easy to operate.
