Analysis of Guinea pig IL-6 by ELISA (CAT#: STEM-MB-1519-LGZ)

Introduction

Interleukin 6(IL-6) is a cytokine with both pro-inflammatory and anti-inflammatory properties. In humans, it is encoded by the IL-6 gene. During infection and after trauma, especially inflammation caused by burns or other tissue damage, IL-6 is secreted by T cells and macrophages to promote the immune response. Studies have shown that IL-6 is required to resist Streptococcus pneumoniae infection in mice, suggesting that IL-6 plays a role in the resistance to infection. IL-6 has been implicated in inflammatory and autoimmune disease progression in many diseases such as diabetes, atherosclerosis, depression, Alzheimer's disease, systemic lupus erythematosus, multiple myeloma, prostate cancer, Behcet's disease, and rheumatoid arthritis. Patients with advanced/metastatic cancer have higher levels of IL-6 in their blood.




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.
