Active Recombinant Cynomolgus CD3E & CD3D Protein, His-Avi-tagged, Biotinylated

• Cat.No.: CD3E & CD3D-516C
• Product Overview: Biotinylated Recombinant Cynomolgus CD3E & CD3D Protein, fused to His and Avi tag, was expressed from HEK293.

Specification

• Species: Cynomolgus
• Source: HEK293
• Tag: Avi&His
• Protein Length: Gln 22 - Asp 117 (CD3E) & Phe 22 - Ala 105 (CD3D)
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Bispecific T cell Engager (CD3 X BCMA) at 1 μg/mL (100 μL/well) can bind Biotinylated Cynomolgus CD3E&CD3D Heterodimer Protein, His,Avitag&Tag Free with a linear range of 0.5-3.9 ng/mL.
• Molecular Mass: The protein has a calculated MW of 17.8 kDa (CD3E) and 13.5 kDa (CD3D). Subunit CD3E is fused with a polyhistidine tag and followed by an Avi tag (Avitag™) and subunit CD3D contains no tag at the C-terminus. The reducing (R) heterodimer protein migrates as 21-23 kDa (CD3E) and 19-21 kDa (CD3D) due to glyosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
  >90% as determined by SEC-MALS.
• 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.
