Cat#:RP-0839H;Product Name:Recombinant Human IGFBP3 / IBP3 Protein (His Tag);Synonym:BP-53,IBP3;Description:A DNA sequence encoding the mature form of human IGFBP3 (NP_000589.2) (Gly28-Lys 291) was fused with a polyhistidine tag at the N-terminus. Recombinant human IGFBP3 protein is purified by our unique chromatographic techniques.;Source:Human Cells;Predicted N Terminal:His 1;Molecular Characterization:The secreted recombinant human IGFBP3 protein comprises 280 amino acids with a predicted molecular mass of 31 kDa. As a result of glycosylation, the apparent molecular mass of rhIGFBP3 is approximately 40-45 kDa in SDS-PAGE under reducing conditions.;Purity:Greater than 85 % as determined by SDS-PAGE;Endotoxin:< 1.0 EU per ug of the recombinant human IGFBP3 protein as determined by the LAL method;Bioactivity:Please contact us for detailed information;Formulation:Recombinant human IGFBP3 protein was lyophilized from sterile PBS, pH 7.4;Stability:Recombinant human IGFBP3 Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:Please see related COA for specific instructions.;Storage:Avoid repeated freeze-thaw cycles. In lyophilized state for 1 year (4-8℃); Upon reconstitution under sterile conditions for 2 weeks (4-8℃) or 3 months (-20℃ to -70℃).;
