Recombinant Human Interleukin 7, His tagged

Cat.No.: IL7-67H
Product Overview: Human recombinant protein expressed in Nicotiana benthamiana. It is produced by transient expression in non-transgenic plants and is purified by sequential chromatography (FPLC). rHuman Interleukin 7 is a glycosilated polypeptide chain containing 160 amino acids (26 -177 of P13232 IL7_HUMAN ), fused to His tag at N-terminal. rHuman IL-7 migrate at approximatly 18–25 kDa by SDS-PAGE. This product contains no animal-derived components or impurities. Animal Free product.
Description: Interleukin-7 (IL-7) is a member of the interleukin family which regulates the development and survival of lymphoid and myeloid cells. It has a potent effect for the stimulation of the adaptative immune response, it promotes proliferation of lymphoid progenitors (Pre-B, Pro-B and early T cells), and the effects include mobilization, maturation, and maintenance of IL-7 responsive immune cells.The biological functions of IL-7 as a key "lymphotrophin" in JAK-STAT pathways, PI3 kinase pathway, and Src kinase pathway. IL-7 has also been shown to play a vital role in energy metabolism of T cells and regulating glucose uptake in T lymphocytes through Glut1 via activation of STAT5 and Akt. It has a thymic antiapoptotic effect, and induce the expression of antiapoptotic proteins Bcl-2 and Mcl-1 and the inhibition of preapoptotic proteins Bax and Bad. IL-7 has potential therapeutic applications for the lymphoid reconstitution of immuno-depressed patients (chemotherapy, radiation, AIDS, and bone marrow transplant).
