Recombinant Protein;1MG;Human CD3E&CD3D Heterodimer Protein, Llama Fc&Llama Fc, low endotoxin (CDD-H5258) is expressed from human 293 cells (HEK293). It contains AA Asp 23 - Asp 126 (CD3E) & Phe 22 - Ala 105 (CD3D) (Accession # P07766-1 (CD3E) & P04234-1 (CD3D)).;Human CD3E & CD3D Heterodimer Protein, Llama IgG2b Fc Tag & Llama IgG2b Fc Tag, low endotoxin is produced by co-expression of CD3E and CD3D, has a calculated MW of 42.9 kDa (CD3E) and 40.8 kDa (CD3D). Subunit CD3E is fused with a llama IgG2b Fc tag at the C-terminus and subunit CD3D is fused with a llama IgG2b Fc tag at the C-terminus. The predicted N-terminus is Asp 23 (CD3E) & Phe 22 (CD3D). The reducing (R) protein migrates as 50-60 kDa due to glycosylation.;Immobilized Human CD3E&CD3D Heterodimer Protein, Llama Fc&Llama Fc, low endotoxin (Cat. No. CDD-H5258) at 2 μg/mL (100 μL/well) can bind SP34-2 (mouse IgG1) with a linear range of 1-20 ng/mL (Routinely tested).
