Cat#:RP-021AC;Product Name:Recombinant Human CD3 epsilon & CD3 delta Heterodimer Protein;Synonym:CD3E & CD3D,CD3 delta & CD3 epsilon,CD3 delta / epsilon;Description:Human CD3 epsilon & CD3 delta Heterodimer Protein with Asp 23 - Asp 126 (CD3E with P07766) and & Phe 22 - Ala 105 (CD3D with P04234) with was produced in HEK293 cells.;Source:HEK293;Predicted N Terminal:Asp 23 (CD3E) & Phe 22 (CD3D);Molecular Characterization:Recombinant Human CD3 epsilon & CD3 delta Heterodimer Protein CD3E(Asp 23 - Asp 126)P07766Poly-hisCD3D(Phe 22 - Ala 105)P04234Human CD3 epsilon & CD3 delta Heterodimer Protein is produced by co-expression of CD3E and CD3D, has a calculated MW of 16.7 kDa (CD3E), 13.5 kDa (CD3D) . Subunit CD3E is fused with a polyhistidine tag at the C-terminus and subunit CD3D contains no tag. The predicted N-terminus is Asp 23 (CD3E) & Phe 22 (CD3D). The reducing (R) heterodimer protein migrates as 24-32 kDa (CD3E) and 22 kDa (CD3D) due to glycosylation.;Purity:Greater than 90% as determined by SDS-PAGE.;Endotoxin:< 1.0 EU per μg of recombinant human CD3 epsilon & CD3 delta Heterodimer protein by the LAL method.;Formulation:Recombinant human CD3 epsilon & CD3 delta Heterodimer protein was lyophilized from 0.22 μm filtered solution in PBS, pH7.4.;Stability:Recombinant human CD3 epsilon & CD3 delta Heterodimer protein was stable up to 1 year from date of receipt at -70℃;Storage:Store recombinant human CD3 epsilon & CD3 delta Heterodimer protein under sterile conditions at -20℃ to -80℃. It is recommended that the recombinant protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.;Usage:For Lab Research Use Only;
