451Lu BR Viable Cells (1 million 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. 451Lu BR is a human metastatic melanoma cell line. This cell line is resistant to BRAF and MEK inhibitors. This cell line features the specific V600E (Val600Glu) mutation at codon 600 in the BRAF gene. This mutation causes constitutively active kinase activity and activation of MEK and ERK signaling pathway. This cell line was derived from the same patient as the cell lines, WM164, and 451Lu. 451Lu BR cells produce xenograft tumors when injected into immunocompromised mice.
