CD3E&CD3D, His, Human

CD3E&CD3D, His, Human

The T-cell surface glycoproteins CD3E and CD3D, also called CD3 epsilon and CD3 delta chain, are single-pass type I membrane proteins. When antigen presenting cells (APCs) activate the T-cell receptor (TCR), TCR signals are transmitted by the CD3 chains CD3D, CD3E, CD3G, and CD3Z. All CD3 chains have immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain.

Expression System HEK293
Theoretical Molecular Weight 17.9 kDa for CD3E
16.7 kDa for CD3D
Apparent Molecular Weight Due to glycosylation, the protein migrates to 28-38 kDa and 25 kDa based on Bis-Tris PAGE result.
Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage & Stability Upon receiving, the lyophilized product remains stable up to 6 months at -20 °C or below as supplied from date of receipt.
-80°C for 3 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
