Active Recombinant Human CD3E & CD3D protein, His-tagged

• Cat.No.: CD3E & CD3D-203H
• Product Overview: Recombinant Human CD3E & CD3D protein(P07766(CD3E)&P04234(CD3D))(Asp23-Glu120 (CD3E)&Phe22-Ala105 (CD3D)) is expressed from Expi293 with His tag at the C-terminal.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human CD3E&CD3D at 2μg/ml (100μl/Well) on the plate. Dose response curve for OKT3, mFc Tag with the EC50 of 38ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 17.9 kDa (CD3E) and 16.7 kDa (CD3D). Due to glycosylation, the protein migrates to 35-42 kDa and 25 kDa based on Tris-Bis PAGE result.
• Protein Length: Asp23-Glu120 (CD3E)&Phe22-Ala105 (CD3D)
• Endotoxin: Less than 1EU per μg by the LAL method.
• Purity: > 95% as determined by Tris-Bis PAGE
  > 95% as determined by HPLC
• Storage: -20 to -80°C for 12 months as supplied from date of receipt.
  -20 to -80°C for 3-6 months in unopened state after reconstitution.
  2-8°C for 2-7 days after reconstitution.
  Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.
• Reconstitution: Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
