Recombinant Human KRAS protein, His-tagged

• Cat.No.: KRAS-19H
• Product Overview: Recombinant Human KRAS protein(Met 1 - Lys 169) (P01116-2), fused to N-terminal His tag, was expressed in Insect cells.

Specification

• Source: Insect cells
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 0.5 M NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
• Molecular Mass: The protein has a calculated MW of 21.3 kDa. The protein migrates as 23-25 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Protein length: Met 1 - Lys 169
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Storage: This product is stable after storage at:
  -20°C to -70°C for 12 months in lyophilized state;
  -70°C for 3 months under sterile conditions after reconstitution.
• 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.
