Identification of epitopes recognized by CD44 v6-specific antibodies.

The CD44 exon v6 sequences of human (A), rat (B), and mouse (C) are shown.42 Underlined are the epitopes recognized by the human-specific antibody VFF18,11 the rat-specific antibody 1.1ASML,43 and the murine-specific antibody 9A4, as determined by peptide mapping. The gray areas identify conserved amino acids.
