Bispecific Therapeutics Explained

2024-12-03T11:54:39-05:00June 28th, 2021|Articles|

Bispecific therapeutics are monoclonal antibodies that carry a specific antigen-binding capability on each arm. Bispecifics are thus capable of having two specificities that can either double the binding affinity of the antibody toward the same antigen (increased avidity), or can now bind to two targets. Bispecifics are most often described as two types: trispecifics and bispecific T-cell engaged antibodies (BiTE).
