GMP Recombinant Human IL2 Protein

• Cat.No.: IL2-150HGB
• Product Overview: Recombinant mature form of human IL-2 (P60568-1) (Ala21-Thr153) was expressed and purified, with an initial Met in an animal component free process under cGMP guidelines. The purified protein was biotinylated in vitro.

Specification

• Species: Human
• Source: E.coli
• Protein Length: 21-153 a.a.
• Predicted N Terminal: Met
• Form: Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5 % mannitol and 0.01% Tween80.
• Molecular Mass: The GMP recombinant human IL-2 consists of 134 amino acids and has a calculated molecular mass of 15.5 kDa as predicted in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
