FUCA2 and fibrosarcoma: We applied the FUCA1 specific antibodies A112 and A180, as well as a commercially available polyclonal rabbit antibody against FUCA2, to analyze cell lysates derived from the human fibrosarcoma cell line HT1080, HeLa cells and HEK293FT cells after transient transfection with the FUCA1-H6 and the corresponding FUCA2-H6 construct (Figure 3C).
