Active Recombinant Human CD19 protein, His-tagged

• Cat.No.: CD19-150H
• Product Overview: Recombinant Human CD19 protein(P15391-1)(Met1-Lys291), fused with His tag, was produced in Human Cells.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from sterile PBS, pH 7.4
• Bio-activity: Immobilized Human CD19 His at 2 μg/ml (100 μl/well) can bind Anti-CD19 Antibody, the EC50 of Anti-CD19 Antibody is 5-40 ng/mL.
• Molecular Mass: The recombinant human CD19 consists of 283 amino acids and predictes a molecular mass of 31.6 kDa. In SDS-PAGE under reducing conditions, rhCD19 migrates as an approximately 47 kDa band due to glycosylation.
• Protein Length: Met1-Lys291
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• 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.
