Anti-Human CD3xCD19 Bispecific Antibody

 Clone: Blibio     Catalog#: AB5302


In immunology, the co receptor of CD3 (cluster of differentiation 3) T cells is a protein complex. CD3 has five peptide chains, i.e γ Chain δ Chain ε Chain ζ Chain and η Chains, all of which are transmembrane proteins. The transmembrane region of CD3 molecule is connected with the transmembrane region of the two peptide chains of TCR through salt bridge to form the tcr-cd3 complex, which is jointly involved in the recognition of antigen by T cells. The activation signal generated by TCR recognizing antigen is transduced into T cells by CD3. CD19 is a CD molecule (i.e., leukocyte differentiation antigen) expressed by B cells and belongs to the Ig superfamily. All B cell lines except plasma cells, malignant B cells and FDCs express this molecule. It is an important membrane antigen involved in the proliferation, differentiation, activation and antibody production of B cells, and can also promote the signal transduction of BCR.
