Recombinant Protein;1MG;Rabbit CD3E&CD3D Heterodimer Protein, His Tag&Flag Tag (CDD-R52D7) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Thr 120 (CD3E) & Thr 22 - Ser 107 (CD3D) (Accession # Q9TUF9-1 (CD3E) & A0A5F9D3I4-1 (CD3D)).;Rabbit CD3E&CD3D Heterodimer Protein, His Tag&Flag Tag is produced by co-expression of CD3E and CD3D, has a calculated MW of 16.5 kDa (CD3E) and 14.5 kDa (CD3D). Subunit CD3E is fused with a polyhistidine tag at the C-terminus and subunit CD3D is fused with a flag tag at the C-terminus. The reducing (R) protein migrates as 20 kDa due to glycosylation.
