Experimental analysis by site-directed mutagenesis of somatic mutation effects on affinity and fine specificity in antibodies specific for lysozyme.

Abstract excerpt

To experimentally examine the functional roles of somatically derived structural variation in the lysozyme-binding mAb HyHEL-10, we have introduced three different point mutations and one insertion at two different sites in HyHEL-10 by site-directed mutagenesis and expression of the mutant antibodies. Mutation of Asp----Ala at position 101 of the H chain returns a somatically mutated residue to its germline...
