Application: Chemiluminescence Immunoassay (CLIA) New CLIA kits from USCNK life science Chemiluminescence immunoassay (CLIA) is now established as the best alternatives to conventional ELISA assays for the quantitation of low concentrations of analytes in complex samples. The performance of CLIAs far exceeds that of ELISA tests. Additionally, the protocol is faster, does not require stopping reagents and provides a broader assay range. »All Chemiluminescence Immunoassays (CLIA). »All USCN Life Science products.
