Cat#:RP-4089H;Product Name:Recombinant Human IL9 Protein, HEK;Synonym:P40, HP40, T-cell growth factor p40, IL-9, P40 cytokine.;Description:IL-9 Protein produced in HEK cells is a glycosylated monomer, having a molecular weight range of 38-48kDa due to glycosylation. The IL9 is purified by proprietary chromatographic techniques.;Source:HEK.;Purity:Greater than 95% as obsereved by SDS-PAGE.;Bioactivity:The specific activity was determined by the dose-dependent stimulation of the proliferation of human MO7e cells (human megakaryoblastic leukemia cell line) and is typically 0.03-0.2ng/ml.;Formulation:The IL9 was lyophilized from 1mg/ml in 1xPBS.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized IL-9 in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized?IL-9 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL9 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
