Purity ~90% (SDS-PAGE). IL7R, also known as interleukin-7 receptor, is a hematopoietin receptor superfamily member. It plays important role in lymphocyte differentiation, proliferation, multiple sclerosis, and survival. This protein signaling is essential for T-cell development and regulation of native and memory T-cell homeostasis. Also, it is critically required for the proper development and function of lymphoid cells. Recombinant human IL7R, fused to hIgG-His-Tag at C-terminal, expressed in insect cell and purified by using conventional chromatography techniques. Source: Recombinant protein corresponding to aa21-239 of human IL7R, fused to hIgG-His-Tag at C-terminal, expressed in insect cell. Molecular Weight: ~52.5kD (461aa), ~50-70kD (SDS-PAGE under reducing conditions) Endotoxin: <1EU/1ug (determined by LAL method) AA
