The Recombinant Human CD3 epsilon Protein is a biologically active recombinant protein that plays a significant role in various cellular processes and signaling pathways in human biology. This protein is widely employed in immunological research, cell biology studies, protein-protein interaction analyses, and therapeutic development, providing researchers with a reliable tool for investigating CD3 epsilon function and its implications in health and disease.
This product (SKU: RPCB0719) is produced using HEK293 cells and features a C-hFc tag for convenient detection and purification. The protein exhibits a calculated molecular weight of 36.1 kDa with an observed molecular weight of 35-55 kDa under denaturing conditions, achieving ≥ 95 % as determined by SDS-PAGE., ensuring exceptional quality and consistency for research applications.
High quality, high purity and low endotoxin recombinant Recombinant Human CD3 epsilon Protein (RPCB0719), tested reactivity in HEK293 cells and has been validated in SDS-PAGE.100% guaranteed.
Endotoxin:
< 1 EU/μg of the protein by LAL method.
Purity:
≥ 95 % as determined by SDS-PAGE.
Formulation:
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
T-cell surface glycoprotein CD3 epsilon & CD3 gamma chain, also known as CD3E & CD3G, are single-pass type I membrane proteins.When antigen presenting cells (APCs) activate T-cell receptor (TCR), TCR-mediated signals are transmitted across the cell membrane by the CD3 chains CD3D, CD3E, CD3G and CD3Z. All CD3 chains contain immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain.
Recombinant Human CD3 epsilon Protein was determined by Tris-Bis PAGE under reducing conditions.
Immobilized Human CD3E, hFc Tag at 1 μg/mL (100 μL/Well) on the plate. Dose response curve for Biotinylated Anti-CD3 Antibody, hFc Tag with the EC50 of 33.5ng/mL determined by ELISA (QC Test).
