Biotinylated Human CD3E&CD3D/CD3 epsilon&CD3 delta Protein (Primary Amine Labeling)
Recombinant Biotinylated Human CD3E&CD3D/CD3 epsilon&CD3 delta Protein (Primary Amine Labeling) is expressed from HEK293 with His tag at the C-Terminus. It contains Asp23-Asp126 (CD3E)&Phe22-Ala105 (CD3D) [Accession | P07766 (CD3E)&P04234 (CD3D)].
The protein has a predicted MW of 17.9 kDa (CD3E) and 16.7 kDa (CD3D). Due to glycosylation, the protein migrates to 25-40 kDa based on Bis-Tris PAGE result.
>95% as determined by Bis-Tris PAGE
>95% as determined by HPLC
Less than 1 EU per μg by the LAL method.
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Biotinylated Human CD3E&CD3D on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
The purity of Biotinylated Human CD3E&CD3D is greater than 95% as determined by SEC-HPLC.
Immobilized Biotinylated Human CD3E&CD3D, His Tag at 0.5 μg/ml (100 μl/well) on the streptavidin precoated plate (5 μg/ml). Dose response curve for OKT3, mFc Tag with the EC50 of 35.2 ng/ml determined by ELISA (QC Test).
T-cell surface glycoprotein CD3 epsilon&CD3 delta chain, also known as CD3E&CD3D, 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.
