Cat#:RP-4060H;Product Name:Recombinant Human IL29 Protein, HEK;Synonym:Interleukin-29, IL-29, IFN-Lambda 1, Interferon-Lambda 1, Cytokine ZCYTO21, IL29, IFNL1, ZCYTO21.;Description:IL-29 Protein produced in HEK cells is a glycosylated monomer, having a molecular weight range of 29-35kDa due to glycosylation. The IL-29 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 protection of the cytopathic effect on A549 cells (human lung adenocarcinoma epithelial cell line) that were challenged with encephalomyocarditis (EMC) virus and is typically 0.5-5ng/ml.;Formulation:The IL29 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-29 in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized?IL-29 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL29 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.;
