Recombinant Human KITLG protein(Met1-Ala189), His-tagged

• Cat.No.: KITLG-558H
• Product Overview: Recombinant Human SCF (P21583-1)(Met 1-Ala 189) was expressed in Insect Cells, with a polyhistidine tag at the C-terminus.

Specification

• Species: Human
• Source: Insect Cells
• Tag: His
• Protein Length: 1-189 a.a.
• Form: Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 8.0. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. The ED50 for this effect is 1-5 ng/mL.
• Molecular Mass: The secreted recombinant human SCF (aa 1-189) consists of 175 amino acids and predicts a molecular mass of 19.9 kDa. The apparent molecular mass of rh SCF is approximately 22 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 92 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
