Recombinant Human B2M protein, His-tagged

• Cat.No.: B2M-1656H
• Product Overview: Recombinant Human B2M protein (Met 1-Met 119), fused to His tag at C-terminus, was expressed in human 293 cells (HEK293).

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from sterile PBS, pH 7.4
• Molecular Mass: The recombinant human B2M consists of 110 amino acids and migrates as an approximately 13.2 kDa band in SDS-PAGE under reducing conditions as predicted.
• Protein length: Met 1-Met 119
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 97 % 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.
