Anti-βGal-hCD3

Anti-βGal-hCD3 is a bispecific antibody that binds to two sites: E. coli β-galactosidase (β-Gal)and hCD3, part of the T cell receptor. It is used as a negative control for Anti-hCD19-CD3 bispecific antibody that, alike Blinatumomab, engages unstimulated T cells to proliferate and exert cytotoxic activity on CD19-positive lymphoma cells [1,2].
