重组人 CD3D & CD3E Heterodimer蛋白 (PE定点偶联, Flag & His 标签)

重组人CD3D & CD3E Heterodimer蛋白（PE定点偶联, Flag & His标签）（产品说明）
蛋白名称：Human CD3D & CD3E Protein (Site-Specific PE Conjugation, Flag & His)
蛋白构建：A DNA sequence encoding the human CD3D (P04234-1) (Met1-Ala105) was fused with a C-terminal Flag tag. Another DNA sequence encoding the human CD3E (P07766-1) (Met1-Asp126) was fused with a C-terminal polyhistidine tag. The two plasmids were co-expressed and the human CD3D/CD3E heterodimer was purified. The protein is site-specifically conjugated with PE (Excitation= 495 - 566 nm, Emission Max.= 575 nm).
表达宿主：HEK293 Cells
蛋白活性：1.Flow cytometric analysis of anti-CD3(OKT3 derived) CAR expression. 5e5 of anti-CD3(OKT3 derived) CAR-293 cells were stained with 100 μL of 1:100 (1 μL stock solution in 100 μL FACS buffer) of PE-conjugated human CD3D & CD3E Heterodimer Protein (Site-Specific PE Conjugation, Flag & His Tag, Cat. No. CT038-H2586H-SP) and negative control protein. Non-transduced 293 cells were used as a control (left). PE signal was used to evaluate the binding activity (QC tested). 2.Binding activity of PE-conjugated CD3D & CD3E protein to PBMC cells. PBMC cells were stained with FITC conjugated anti-CD3 antibody and PE-conjugated human CD3D & CD3E Heterodimer Protein (Site-Specific PE Conjugation, Flag & His Tag, Cat. No. CT038-H2586H-SP) and detected by flow cytometry. FITC signal was used to evaluate the content of CD3+ T cells in PBMCs. PE signal was used to evaluate the non-specific binding activity to PBMCs (QC tested).
蛋白内毒素：< 1.0 EU per μg protein as determined by the LAL method.
