Description: This High Sensitivity ELISAs enables the analysis of Interleukin-2 in low concentrations from serum, plasma, or cell culture samples.
eBioscience High Sensitivity ELISA Kits offer accurate quantification below conventional ELISA limits. This is made possible by ther inherent design by amplifying the signal generated by the enzyme horseradish peroxidase (HRP) and the colorimetric-detectable substrate tetramethylbenzidin (TMB) based on Tyramide Signal Amplification (TSA) technology*.
IL-2 plays a central role in the activation and proliferation of lymphocytes that have been primed by antigens. IL-2 plays a pivotal role in for the expansion of most T-cells, natural killer cells and B-cells during certain phases of their response. IL-2 is a 15 kDa glycoprotein encoded by a single gene located in the q26-28 region of human chromosome 4. The cDNA deduced polypeptide consists of 153 amino acids. Apart from its most important role to mediate antigen-specific T-lymphocyte proliferation, IL-2 modulates the expression of interferon gamma and major histocompatibility antigens, stimulates proliferation and differentiation of activated B-cells, augments natural killer cell activity and inhibits granulocyte-macrophage colony formation. IL-2 displays antitumoral effects, thus being used in cancer therapy. Monitoring of IL-2 levels in serum provides more detailed insights in several pathological situations such as cancer, infectious diseases, transplant rejection, multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus and type I diabetes.
*High Sensitivity ELISAs are based on a patent from PerkinElmer LAS, patent number 5,731,158; 5,583,001; 5,196,306.
