Recombinant Human IL-2 Protein (C09-1095-686)

Purity≥95% (SDS-PAGE, SEC-HPLC) Additional sequence information133 amino acidsFunctionInterleukin-2, or interleukin-2, is also known as T cell growth factor (TCRF). A wide range of bioactive cytokines produced primarily by activated CD4+T cells and CD8+T cells. It is a growth factor of all T cell subsets, which can make T cells survive in vitro for a long time and promote the proliferation of activated B cells. Therefore, it is an important factor in the regulation of immune response, and also involved in antibody response, hematopoietic and tumor surveillance.Produced by T-cells in response to antigenic or mitogenic stimulation, this protein is required for T-cell proliferation and other activities crucial to regulation of the immune response. Can stimulate B-cells, monocytes, lymphokine-activated killer cells, natural killer cells, and glioma cells.This product is a recombinant protein expressed by eukaryotic cells. The protein gene was inserted into stable expression vector and transformed into CHO-K1 cells. After cloning, screening and quality verification, the selected stable expression strain was prepared by fermentation of the medium determined by chemical composition (without any animal source components).This product is a sterile lyophilized powder, made from a protein solution containing 10mM phosphate with a pH of 7.2 filtered by 0.2μm. Specifications and Purity: GMP, ≥95% (SDS-PAGE, SEC-HPLC), Active, CHO-K1, His, 21-153 aa.
