Exploring the world of antibodies: mAbs, Fabs, dAbs, and bsAbs
There is a vast array of antibody variants, including multispecific (msAb), bispecific antibodies (bsAb), antibody fragments (Fab, dAb, scFv), and antibody-drug conjugates (ADC). But with this…

Single-Domain Antibodies for Brain Targeting
IgG, the main serum antibody, the intact form of which is almost exclusively used in therapeutic antibodies, is a Y-shaped, multidomain protein with antigen-binding sites located on the two Fab (antig…

Modeling the Degradation of mAb Therapeutics
Cleavage of the peptide bond (hydrolysis) at the mAb’s hinge region leads to the formation of Fc -Fab and Fab species (22).
Responses from different classes of the mAb molecules vary with resp…
