Immobilized Human CD3E&CD3D Heterodimer Protein at 1 μg/mL (100 μL/well) can bind Monoclonal Anti-Human CD3 Antibody, Mouse IgG2a (Clone: OKT3), premium grade with a linear range of 0.2-3 ng/mL.Immobilized Human CD3E&CD3D Heterodimer Protein at 1 μg/mL (100 μL/well) can bind UCHT1 with a linear range of 0.1-3 ng/mL.Immobilized Human CD3E&CD3D Heterodimer Protein at 1 μg/mL (100 μL/well) can bind SP34-2 with a linear range of 0.4-3 ng/mL. |
| Molecular Mass : |
Human CD3E&CD3D Heterodimer Protein is produced by co-expression of CD3E and CD3D, has a calculated MW of 40.2 kDa (CD3E) and 37.3 kDa (CD3D). Subunit CD3E is fused with a human IgG1 Fc tag and a polyhistidine tag at the C-terminus and subunit CD3D is fused with a human IgG1 Fc tag and a flag tag at the C-terminus. As a result of glycosylation, the heterodimer protein migrates as 45-60 kDa under reducing (R) condition, and 100-116 kDa under non-reducing (NR) condition (SDS-PAGE). |
| Endotoxin : |
Less than 1.0 EU per μg by the LAL method. |
| Purity : |
>95% as determined by SDS-PAGE. |
| Storage : |
For long term storage, the product should be stored at lyophilized state at-20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after storage at:-20°C to-70°C for 12 months in lyophilized state;-70°C 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°C before opening to recover the entire contents. |
