Product Properties Alternative Names SCFR, PBT, CD117, ckit, c-kit, EC 2.7.10, EC 2.7.10.1, KIT Species Human Expression Sequence Gln26-Pro520 Accession P10721-2 Tag C-His-Avi Expression System HEK293 Molecular Weight The protein has a predicted MW of 58.60 kDa. Due to glycosylation, the protein migrates to 75-105 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 【ELISA Data】Immobilized Human SCF, No Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human CD117, His Tag with the EC50 of 6.8μg/ml determined by ELISA. 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 ~ -15℃, valid for 1 year after receipt. After reconstitution, store at -85 ~ -65℃ under sterile conditions, valid for 3 months.
