Validation Data Gallery

• 

  Purity of recombinant human IL-7 was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

• 

  Recombinant human IL-7 (HZ-1281) stimulates dose-dependent proliferation of the 2E8 murine B Lymphocyte cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. 2E8 cells were treated with increasing concentrations of recombinant IL-7 for 120 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.1-1.4 ng/mL.

Background

Interleukin-7 (IL7) is a cytokine involved in B and T cell development. It plays an active role in the development, survival, maintaining and restoring homeostasis of mature T lymphocytes and is a key regulator of the commitment, survival, proliferation and maturation of B cells during development. Furthermore, IL7 can improve the antiviral function and expansion of natural killer (NK) cells and regulate the development and differentiation of dendritic cells. IL7 has also been reported as a regulator of the development of central nervous system and myogenesis and skeletal muscle cell migration (PMID: 29663382; 29655570; 29449560)
