产品描述

IL7 produced in Sf9 Baculovirus cells is a single,glycosylated polypeptide chain containing 161 amino acids (26-177 a.a.) andhaving a molecular mass of 18.4kDa (Molecular size on SDS-PAGE will appear atapproximately 18-28 kDa). IL7 is expressed with a 6 amino acid His tag atC-Terminus and purified by proprietary chromatographic techniques.

Introduction

IL-7 is a cytokine important for B and T cell development. This cytokine and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. This cytokine is found to be a cofactor for V(D)J rearrangement of the T cell receptor beta (TCRB) during early T cell development. This cytokine can be produced locally by intestinal epithelial and epithelial goblet cells, and may serve as a regulatory factor for intestinal mucosal lymphocytes. Knockout studies in mice suggested that this cytokine plays an essential role in lymphoid cell survival.

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
