Active Recombinant Human IL2 protein, Low Endotoxin

• Cat.No.: IL2-502H
• Product Overview: Recombinant Human IL2 protein(P60568)(Ala21-Thr153) was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Non
• Protein Length: 21-153 aa
• Form: Lyophilized from 0.22 μm 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 CTLL‑2 mouse cytotoxic T cells. The ED50 for this effect is 0.5-2 ng/mL.
• Molecular Mass: The protein has a predicted MW of 15.41 kDa. Due to glycosylation, the protein migrates to 16-20 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 24 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.
