Human CD3E&CD3G Heterodimer Protein, His Tag&Tag Free AIDD-Ready protein is designed for direct use in SPR assays. It is supplied in a sugar-free, glycerol-free formulation to eliminate refractive index interference in SPR. No desalting or buffer exchange is required before use, simplifying the SPR workflow and supporting high-throughput experimental validation to accelerate the transition from AI prediction to wet-lab validation.
CD3 epsilon & CD3 gamma, CD3E & CD3G
Human CD3E&CD3G Heterodimer Protein, His Tag&Tag Free (CDG-H52W5AI) is expressed from human 293 cells (HEK293). It contains AA Asp 23 - Asp 126 (CD3E) & Gln 23 - Ser 116 (CD3G) (Accession # NP_000724.1 (CD3E) & AAI13831 (CD3G)).
Predicted N-terminus: Asp 23 (CD3E) & Gln 23 (CD3G)

The protein has a calculated MW of 16.9 kDa (CD3E) & 14.6 kDa (CD3G). The protein migrates as 19 kDa, 21 kDa and 26-27 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
The protein is designed as a heterodimer.
