Enzyme-linked immunosorbent assay (ELISA) is a biochemical procedure in immunology used primarily to determine the presence of antigens or antibodies in a sample. For years, ELISA has been used as a diagnostic tool in plant pathology and medicine. It has test kits that are used for cancer, autoimmune diseases, fertility, thyroid, steroids, infectious diseases and parasitology, allergies, and diabetes.
One of the PLAT/TPA ELISA Kit for cancer is prostatic acid phosphatase (PAP), which is used to measure prostatic acid phosphatase (PAP) in the serum and plasma of a human. The components of the kit are designed for use as an integral unit only. Therefore, components from different lots should be segregated. It is specifically designed for the quantitative detection of prostate-specific antigen (PSA) in human serum.
Another example of a test kit is the human allergen-specific IgE ELISA assay, which is used to quantify and quantify allergen-specific human immunoglobulin E. The total IgE of the sample is determined before performing the allergen-specific IgE assay. Human growth hormone (HGH), another type of test kit, is used to test a woman's fertility. It determines the human growth hormone concentration within the human serum.
There are also test kits for infectious diseases and one of these is Bordetella pertussis IgA, which is used to determine specific IgA antibodies against Bordetella pertussis in plasma and serum. The assay is designed for in-vitro diagnostic testing only. Therefore, further tests should be taken into account.
There are many manufacturers of ELISA kits and one of them is Shanghai PZ Bio-Tech Co., Ltd in China. Another ELISA kit manufacturer is Taiwan Advance Bio-Pharm Inc., based in Taiwan. Other manufacturers of ELISA kits are Wuhan Boster Biological Technology, Ltd. (China), Green House Pharm Pte Ltd (Singapore), and Biocare Diagnostics Ltd. (China).
