Rat anti Mouse CD44v6, clone 9A4 recognizes an epitope encoded by exon v6 on the variant portion of murine CD44. CD44v6 has been identified along with ICAM-1 as a co-receptor for Met and in mammary epithelia appears to act at the primary Met co-receptor (Di-Cicco et al. 2015).

Rat anti Mouse CD44v6, clone 9A4 has been used successfully for the identification of CD44v6 expressing cells by immunofluorescence (Di-Cicco et al. 2015), western blotting (Lo et al. 2012). Immunohistochemistry (Weilenga et al. 1999) along with ELISA and flow cytometry (Weiss et al. 1997).
