CD44v4 antibody | VFF-11
Detection of total CD44 and variant CD44 protein. Representative figures of immunostaining with all cells stained positive in this field (A), western blotting (B), and flow cytometry (C). (A) Immunostaining of HN12 cells for total CD44, an isotype matched control, v3, v4, v5, and v6. (B) Western blotting lanes 1–12 contain MW marker, HaCaT, HN4, HN12, HN8, HN22, HN30, HN31, OSC-19, OSC-20, DT, and Namalwa cells, repectively. (C) flow cytometry results for HN4 and HN12 cells detecting v7 and v10.

Antibody Quality and Performance Guarantee
| Mouse anti Human CD44v4 antibody, clone VFF-11 recognizes an epitope encoded by exon v4 on the variant portion of human CD44. CD44v4 is strongly expressed on some breast cancer cell lines, notably epithelial-like BT-20 cells where v4 containing isoforms possess functional E-selectin ligand activity mediating cell adhesion under physiological flow conditions (Shirure et al. 2014). |
