PBL is a leading developer and manufacturer of immunoassays for the detection and quantification of Type I and III IFN in various species. These ELISA kits are heterogeneous antibody sandwich assays providing varying levels of sensitivity and robustness. The detection system utilizes horseradish peroxidase (HRP) and Tetramethyl-benzidine (TMB) is the enzyme substrate.

Human Interferon ELISAs
