FLJ18683, T3E, TCRE, CD3E, CD3-epsilon
Human CD3 epsilon, His Tag (CDE-H5223) is expressed from human 293 cells (HEK293). It contains AA Asp 23 - Asp 126 (Accession # P07766-1).
Predicted N-terminus: Asp 23
This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 16.9 kDa. Maybe caused by unknown PTMs, the protein migrates as 18-19 kDa and 21-22 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition, and 35-43 kDa under non-reducing (NR) condition (SDS-PAGE).
The protein is designed as a dimer.
Human CD3 epsilon, His Tag(CDE-H5223) was digested with trypsin and characterized by LC-MS/MS peptide mapping, achieving chain1: 100% and chain2: 100% sequence coverage (Routinely tested).
Less than 0.01 EU per μg by the LAL method / rFC method.
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
