Recombinant human CD3 monoclonal antibody (mAb) is a high-purity antibody produced in CHO cells to ensure consistent performance and human-like post-translational modifications. Supplied in a tag-free format, this antibody preserves the native sequence and bioactivity, making it well-suited for sensitive immunological studies and T-cell–based assays.

CD3 is a critical component of the T-cell receptor (TCR) complex, playing a central role in T-cell activation, signaling, and immune regulation. Recombinant CD3 mAb is widely used for T-cell stimulation, proliferation assays, immunotherapy development, and immune cell functional studies.
