WM3670 Viable Cells

Cells are sterile, validated by short tandem repeat profiling, and are tested as negative for mycoplasma. It is recommended that cell lines are tested for mycoplasma contamination and short tandem repeat (STR) profiling every 10 passages or each time a frozen seed stock is made. See cell culture protocol for additional details. WM3670 is a metastatic human melanoma cell line with epithelial morphology. This cell line features the G469E mutation at codon 469 in the BRAF gene. The G469E mutation results in an amino acid substitution at position 469 in BRAF, from a glycine (G) to a glutamic acid (E). This mutation occurs within the highly conserved GXGXXG motif of the kinase domain. Most mutant BRAF proteins have increased kinase activity and are transforming in vitro. This cell line contains a G12D mutation at position 12 in the N-RAS gene. The G12D mutation results in an amino acid substitution at position 12 in N-RAS, from a glycine (G) to an aspartic acid (D).
