Recombinant Human KRAS protein(Thr2-Cys185(61Q)), His-tagged

• Cat.No.: KRAS-325H
• Product Overview: Recombinant Human KRAS (P01116-2) (Thr2-Cys185) was expressed in E. coli with a polyhistidine tag at the N-terminus.

Specification

• Source: E. coli
• Species: Human
• Tag: N-His
• Protein length: Thr2-Cys185(61Q)
• Form: Lyophilized from sterile 50 mM Tris, 100 mM glycine, 10 % glycerol, pH 7.5. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant human KRAS consists of 191 amino acids and predicts a molecular mass of 21.9 kDa. It migrates as an approximately 24.1 kDa band 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.
