ViroLabs, Inc. is your ‘one-stop’ and final supplier if you are searching ELISA substrates for your assay development. It offers a full spectrum of all the substrates for commonly used horseradish peroxidase (HRP) and alkaline phosphatase (AP) in most ELISA assays. Our scientists have developed one-component, ready-to-use substrates for all these immobilized enzymes and these high sensitivity, low background substrates have assisted numerous scientists in their assay development and routine ELISA assay performance. Fluorescence-based ELISA (F-ELISA) with 4-MUP (4-methylumbelliferyl phosphate) for AP and ADHP (10-acetyl-3,7-dihydroxyphenoxazine or ‘Amplex Red’) for HRP are generally 5-10 folds more sensitive than the corresponding colorimetric assay. Whether you prefer the absorbance-based or fluorescence–based ELISA assay, our one component, ready-to-use ELISA substrates will not disappoint you. Our ready-to-use TMB (3,3’,5,5’-tetramethylbenzidine) solution has been widely adopted by many research scientists in immunology, virology and epidemiology areas. Cat.
