Specification

• Species: Human
• Source: Insect Cells
• Tag: His
• Protein Length: 19-144 aa
• Form: Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 7.4.
• Bio-activity: Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED50 for this effect is typically 0.2-2 ng/ml.
• Molecular Mass: Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED50 for this effect is typically 0.2-2 ng/ml.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 97 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities 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.
