Product Propertie Alternative Names TDGF1, Cripto, CRGF, CRIPTO, CR Species Human Expression Sequence Leu31-Thr172 Accession P13385 Tag C-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 16.92 kDa. Due to glycosylation, the protein migrates to 23-30 kDa based on SDS-PAGE result. Purity > 95% as determined by SDS-PAGE. 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】Human ACVR1B, hFc Tag captured on CM5 Chip via Protein A can bind Human TDGF1, His Tag with an affinity constant of 0.16 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 Lyophilized powder: Store at -25 to -15°C; stable for 1 year upon receipt.Reconstituted protein: Store under sterile conditions at -85 to -65°C; stable for 3 months.
