Recombinant Human NRAS Protein, His-tagged

• Cat.No.: NRAS-447H
• Product Overview: Recombinant mature form of human NRAS (P01111) (Met1-Cys186) was expressed with a polyhistidine tag at the N-terminus.

Specification

• Source: E.coli
• Species: Human
• Tag: His
• Form: Lyophilized from sterile 50 mM Tris, pH 8.0.
  Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant human NRAS consists of 202 amino acids and predicts a molecular mass of 23 KDa. It migrates as an approximately 24 KDa band in SDS-PAGE under reducing conditions.
• Protein length: Met1-Cys186
• 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℃ before opening to recover the entire contents.
