Validation Data Gallery

  • Purity of recombinant human IL-9 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.

  • GMP Recombinant human IL-9 (HZ-1240-GMP) stimulates dose-dependent proliferation of the MO7e (human megakaryoblastic leukemia) cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. MO7e cells were treated with increasing concentrations of GMP recombinant IL-9 for 72 hours. The EC50 was determined using a 4-parameter non-linear regression model. Activity determination was conducted in triplicate on a validated bioassay. The EC50 range is 0.15-0.85 ng/mL​.

Background

Interleukin 9 (IL-9) is a γc-family cytokine produced by T-helper 9 (Th9) cells. IL-9 promotes the survival and activation of various cellular targets, including mast cells, B cells, T cells, and structural cells. Its expression is considered a hallmark of Th2-lineage cells. Primarily studied in Th2-type immunity, IL-9 was shown to be involved in asthma, allergy, and host defense against helminth infections. IL-9 also stimulates cell proliferation and prevents apoptosis. It functions through the its cognate receptor (IL9R), which activates different signal transducer and activator proteins to execute various biological processes (PMID: 29703631; 29437190; 29392411; 29391143)
