Analysis of IFN-α2a (Non-human primate) by ELISA (CAT#: STEM-MB-0905-LGZ)

Introduction

IFN is divided into three types: α, β, and γ according to its source and structure. IFN-α and IFN-β are secreted by many cell types, including lymphocytes (NK cells, B cells and T cells), macrophages, fibroblasts, bladder cells, osteoblasts, etc. They stimulate macrophages and NK cells to elicit antiviral responses, involve the IRF3/IRF7 antiviral pathway, and also have antitumor activity. IFN-α2a is a subtype of INF-α.




Principle

Enzyme-linked immunosorbent assay (ELISA) is an enzyme-labeled solid phase immunoassay technique. Its basic principle is to bind the antigen (or antibody) to the solid phase carrier, and the antigen (or antibody) and a certain enzyme link to enzyme labeled antigen (or antibody). During detection, the sample to be tested and the enzymic antigen (or antibody) react with the antigen (or antibody) on the solid phase carrier according to certain procedures, and then remove the unreacted part by washing method. After adding the substrate, the substrate is catalyzed by the enzyme on the solid phase carrier to produce colored substances. Through qualitative or quantitative detection of the amount of colored products, the content of the substance to be measured in the sample can be determined.

Applications
