• Cat.No.: Il1b-384R
• Product Overview: Recombinant Rat IL1B (Q63264-1) (Met 1-Ser 268) was expressed in E. coli fused with a polyhistidine tag at the N-terminus.

Specification

• Species: Rat
• Source: E.coli
• Tag: His
• Protein Length: Met1-Ser268
• Form: Lyophilized from sterile 50mM Tris, 500mM NaCl, pH 8.0. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant Rat IL1B comprises 279 amino acids and predicts a molecular mass of 32.1 kDa. The apparent molecular mass of the Rat IL1B is approximately 35 kDa in SDS-PAGE under reducing conditions.
• Purity: > 90 % 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.
