GoldBio growth factors are manufactured for RESEARCH USE ONLY and cannot be sold for human consumption!Recombinant Human Interleukin-15IL-15Interleukin 15IL15Human interleukin-15 (IL15) is expressed by the IL15 gene located on chromosome 4. It shares approximately 97% and 73% sequence identity with simian and murine IL15, respectively. Both human IL15 and simian IL15 are active on murine cells. IL15 is secreted by mononuclear phagocytes, especially macrophages following infection by virus. It possesses a variety of biological functions that include the stimulation and maintenance of cellular immune responses, specifically the responses which regulate natural killer (NK) cell and T-cell activation and proliferation. In addition, IL15 shares many biological properties with IL2, including T, B and NK cell-stimulatory activities. IL15 signals through a complex composed of IL2/IL15 receptor beta chain. Although IL15 lacks sequence homology with IL2, it has been shown that both the beta and gamma chains of the IL2 receptor are utilized for IL15 binding and signaling. In addition, an IL15 specific binding protein has been cloned from a mouse T-cell clone.Formulation: Sterile filtered white lyophilized powder.Sequence: NWVNVISDLK KIEDLIQSMH IDATLYTESD VHPSCKVTAM KCFLLELQVI SLESGDASIH DTVENLIILA NNSLSSNGNV TESGCKECEE LEEKNIKEFL QSFVHIVQMF INTSMW: ~12.9 kDa (114 amino acids) Purity: >97% by SDS-PAGE and HPLC analyses.Biological Activity: Fully biologically active when compared to standard.
