Anti-CD3D Antibody Picoband®

T-cell surface glycoprotein CD3 delta chain is a protein that in humans is encoded by the CD3D gene. The protein encoded by this gene is part of the T-cell receptor/CD3 complex (TCR/CD3 complex) and is involved in T-cell development and signal transduction. The encoded membrane protein represents the delta subunit of the CD3 complex, and along with four other CD3 subunits, binds either TCR alpha/beta or TCR gamma/delta to form the TCR/CD3 complex on the surface of T-cells. Defects in this gene are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (SCIDBNK) . Two transcript variants encoding different isoforms have been found for this gene. Other variants may also exist, but the full-length natures of their transcripts has yet to be defined.

E.coli-derived human CD3D recombinant protein (Position: F22-K171) . Human CD3D shares 66% and 70.7% amino acid (aa) sequence identity with mouse and rat CD3D, respectively.
