WM3622 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. WM3622 is a metastatic human melanoma cell line that display large flat cell morphology. This cell line contains a F337S mutation in the PTEN gene. The codon for phe337 is replaced with a serine residue and this substitution could be highly detrimental to catalysis by PTEN and to its conformational stability. WM3622 cells produce xenograft tumors when injected into immunocompromised mice.
