Recombinant Human ICOSLG Protein, His-tagged

Specification :
| Description : Ligand for the T-cell-specific cell surface receptor ICOS. Acts as a costimulatory signal for T-cell proliferation and cytokine secretion; induces also B-cell proliferation and differentiation into plasma cells. Could play an important role in mediating local tissue responses to inflammatory conditions, as well as in modulating the secondary immune response by co-stimulating memory T-cell function. | Source : E. coli | Species : Human | Tag : His | Molecular Mass : ~30 kDa | AA Sequence : DTQEKEVRAMVGSDVELSCACPEGS RFDLNDVYVYWQTSESKTVVTYHIP QNSSLENVDSRYRNRALMSPAGMLR GDFSLRLFNVTPQDEQKFHCLVLSQ SLGFQEVLSVEVTLHVAANFSVPVV SAPHSPSQDELTFTCTSINGYPRPN VYWINKTDNSLLDQALQNDTVFLNM RGLYDVVSVLRIARTPSVNIGCCIE NVLLQQNLTVGSQTGNDIGERDKIT ENPVSTGEKNAAT | Purity : Transferred into competent cells and the supernatant was purified by NI column affinity chromatography and the purity is > 85% (by SDS-PAGE). | Notes : For research use only, not for use in diagnostic procedure. | Storage : Store at 4 centigrade short term.
