Product Properties Alternative Names IBP-2, IGFBP-2, BP2, AI255832, mIGFBP-2, IGFBP2, IGF-BP53 Species Cynomolgus Expression Sequence Gly33-Gln325 Accession A0A2K5WZA2 Tag C-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 32.83 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on SDS-PAGE result. Purity > 95% as determined by SDS-PAGE and HPLC. Endotoxin < 1.0 EU per μg by the LAL method. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Reconstitution Method Before opening, centrifuge briefly. Reconstitute the lyophilized protein with distilled water to a concentration exceeding 100 μg/mL. Aliquot after initial reconstitution to avoid repeated freeze-thaw cycles. Features High purity, high activity, low endotoxin, high batch-to-batch consistency Storage Store at -25 to -15°C. Once received, the product is valid for one year. After reconstitution, store under sterile conditions at -85 to -65°C. The product is valid for three months.
