Related Product Information for IL-15 active protein
Interleukin (IL) -15 is a pleiotropic cytokine that plays a pivotal role in both innate and adaptive immunity. IL-15 is unique among cytokines due to its participation in a trans signaling mechanism in which IL-15 receptor alpha (IL-15R alpha) from one subset of cells presents IL-15 to neighboring IL-2R beta/gamma (c) -expressing cells. This newly discovered cytokine is produced by a wide variety of cells and tissues and like IL-2, stimulates the proliferation of T-lymphocytes and induces the generation of cytotoxic T-lymphocytes (CTLs) and lymphokine-activated killer (LAK) cells. Recombinant Mouse IL-15 was expressed in E Coli and purified by using conventional chromatography techniques.

NCBI Description

This gene encodes a a pleiotropic cytokine of the interleukin family of proteins that plays important roles in the innate and adaptive cell homeostasis, as well as peripheral immune function. The encoded protein undergoes proteolytic processing to generate a mature cytokine that stimulates the proliferation of natural killer cells. The transgenic mice overexpressing the encoded protein exhibit an increase in the number of memory CD8+ T cells in a naive state and enhanced protection against bacterial infections. Mice lacking the encoded protein exhibit impaired protection against a strain of attenuated Mycobacterium. [provided by RefSeq, Aug 2016]

Uniprot Description

IL15: Cytokine that stimulates the proliferation of T- lymphocytes. Stimulation by IL-15 requires interaction of IL-15 with components of IL-2R, including IL-2R beta and probably IL-2R gamma but not IL-2R alpha. Belongs to the IL-15/IL-21 family. 2 isoforms of the human protein are produced by alternative splicing.

Protein type: Cytokine; Cell cycle regulation; Secreted; Secreted, signal peptide

Cellular Component: nucleoplasm; extracellular space; cell surface; cytoplasm; extracellular region

Molecular Function: hematopoietin/interferon-class (D200-domain) cytokine receptor binding; cytokine activity

Biological Process: positive regulation of interleukin-17 production; positive regulation of natural killer cell proliferation; positive regulation of immune response; NK T cell proliferation; negative regulation of smooth muscle cell proliferation; cell maturation; signal transduction; lymph node development; positive regulation of tyrosine phosphorylation of Stat3 protein; positive regulation of natural killer cell differentiation; extrathymic T cell selection; natural killer cell differentiation; positive regulation of cell proliferation; immune response; regulation of T cell differentiation; positive regulation of T cell proliferation; regulation of defense response to virus by host; hyaluronan metabolic process

Product Notes

The IL-15 il15 (Catalog #AAA201148) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 49-162aa. AAA Biotech's IL-15 can be used in a range of immunoassay formats including, but not limited to, SDS-PAGE, Bioactivity. Researchers should empirically determine the suitability of the IL-15 il15 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: MRGSHHHHHH GMASMTGGQQ MGRDLYDDDD KDRWGSHM NW IDVRYDLEKI ESLIQSIHID TTLYTDSDFH PSCKVTAMNC FLLELQVILH EYSNMTLNET VRNVLYLANS TLSSNKNVAE SGCKECEELE EKTFTEFLQS FIRIVQMFIN TS. It is sometimes possible for the material contained within the vial of "IL-15, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
