Human CD3D/CD3 delta Protein

Product Info

Recombinant Human CD3D/CD3 delta Protein is expressed from Expi293 with His tag at the C-terminal. It contains Phe22-Ala105.[Accession | P04234-1]

Molecular Weight

The protein has a predicted MW of 10.4 kDa. Due to glycosylation, the protein migrates to 15 kDa based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE


Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.


Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.


The product should be stored at -70℃ or -20℃.

Assay Data
Tris-Bis PAGE

Human CD3 delta on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


The purity of Human CD3 delta is greater than 95% as determined by SEC-HPLC.


T-cell surface glycoprotein CD3 delta chain, also known as CD3D, is a single-pass type I membrane protein.In immunology, the CD3 (cluster of differentiation 3) T cell co-receptor helps to activate both the cytotoxic T cell (CD8 naive T cells) and also T helper cells (CD4 naive T cells). It consists of a protein complex and is composed of four distinct chains. In mammals, the complex contains a CD3γ chain, a CD3δ chain, and two CD3ε chains.
