Differential binding of S. mutans by DMBT1 isoforms in saliva
Blots of SDS-PAGE gels with saliva from different individuals with DMBT1 size isoforms I–IV.
(A and B) (A) probed using a biotinylated S. mutans SpaP A, Cnm strain and (B) probed with DMBT1-specific antibodies. The positions of DMBT1 on both blots is indicated. Note that DMBT1 isoform size differences are not seen, as they are not resolved at the SDS-PAGE gel density used before the blotting.
