Recombinant Rat Il2 protein(Ala21-Gln155)

• Cat.No.: Il2-747R
• Product Overview: Recombinant Rat IL2 (P17108) (Ala 21-Gln 155) was expressed and purified in E. coli, with an initial Met at the N-terminus.

Specification

• Species: Rat
• Source: E.coli
• Tag: Non
• Protein Length: 21-155 a.a.
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: 1. Measured by its ability to bind recombinant human IL2Ra-Fc in a functional ELISA. 2. Measured in a cell proliferation assay using CTLL2. The ED50 for this effect is typically 0.5-3 ng/mL.
• Molecular Mass: The recombinant rat IL2 consisting of 136 amino acids and has a calculated molecular mass of 15.6 kDa. It migrates as an approximately 15 kDa band in SDS-PAGE under reducing conditions.
• Purity: > 95 % 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.
