The WM9 melanoma cell line, known to harbor a hemizygous BRAFV600E mutation, was included as a positive control, whereas the LPS510 liposarcoma cell line was included as a negative control line for all BRAFV600E mutated sarcoma cell lines, as it is wild-type for BRAF according to our DNA sequencing data. This evidence concerns the gene BRAF and sarcoma.
