Mouse IL-10 was originally described as Cytokine Synthesis Inhibitory Factor (CSIF) due to its ability to inhibit cytokine production by TH1 clones. IL-10 is expressed in activated CD8+ and CD4+ T cells, activated monocytes, mast cells, and Ly-1 B cells. IL-10 shares over 80% sequence homology with the Epstein-Barr virus protein BCRFI. The functions of IL-10 include inhibition of macrophage-mediated cytokine synthesis, suppression of the delayed-type hypersensitivity response, and stimulation of the TH2 cell response, which results in elevated antibody production.The BioLegend LEGEND MAX(TM) Mouse IL-10 ELISA Kit is a Sandwich Enzyme-Linked Immunosorbent Assay (ELISA) with a 96-well strip plate that is pre-coated with a capture antibody. This kit is specifically designed for the accurate quantitation of mouse IL-10 from cell culture supernatant, serum, plasma, and other biological fluids. It is analytically validated with ready-to-use reagents.
