Active Recombinant Human CD3E & CD3D protein, His-tagged

• Cat.No.: CD3E & CD3D-376H
• Product Overview: Recombinant Human CD3 epsilon & CD3 delta Heterodimer Protein, Asp 23 - Asp 126 (CD3E, P07766) and & Phe 22 - Ala 105 (CD3D, P04234), was produced in human 293 cells (HEK293).

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 . Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human CD3E&CD3D Heterodimer Protein, His Tag&Tag Free at 1 μg/mL (100 μL/well) can bind Monoclonal Anti-Human CD3 Antibody, Mouse IgG2a (Clone: OKT3) with a linear range of 0.2-6 ng/mL.
• Molecular Mass: The protein has a calculated MW of 16.6 kDa (CD3E) and 13.4 kDa (CD3D). Subunit CD3E is fused with a polyhistidine tag at the C-terminus and subunit CD3D contains no tag. The reducing (R) heterodimer protein migrates as 25-30 kDa (CD3E) and 20 kDa and 22 kDa (CD3D) due to glycosylation.
• Protein Length: Asp 23 - Asp 126 (CD3E) & Phe 22 - Ala 105 (CD3D)
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 centigrade to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade 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℃ before opening to recover the entire contents.
