Product Properties Alternative Names IGFBP-7, IBP7, AGM, FSTL2, IGFBP-7v, IGFBPRP1, MAC25, PSF, RAMSVPS, TAF Species Mouse Expression Sequence Ser26-Leu281 Accession Q61581 Tag C-hFc Expression System HEK293 Molecular Weight The protein has a predicted MW of 53.03 kDa. Due to glycosylation, the protein migrates to 55-70 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 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Biological Activity 【SPR Data】Mouse IGFBP-7, hFc Tag captured on CM5 Chip via Protein A can bind Human CD93, His Tag with an affinity constant of 0.59 μM as determined in SPR assay . 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. The shelf life is 1 year from the date of receipt. After reconstitution, store at -85 to -65°C under sterile conditions for up to 3 months.
