Active Recombinant Mouse Il9 protein, His-tagged, Low Endotoxin

• Cat.No.: Il9-1059M
• Product Overview: Recombinant Mouse Il9 protein(P15247)(19-144 aa), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Mouse
• Source: HEK293
• Tag: His
• Protein Length: 19-144 aa
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED50 for this effect is < 3 ng/mL.
• Molecular Mass: The protein has a predicted MW of 15.4 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
• Storage: Store at -20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
