WM3622 Purified Genomic DNA

Genomic DNA was purified from cells using genomic DNA preparaton kit according to manufacturers instruction. DNA was diluted to 200 ng/µL in TE buffer (0.01 M Tris Chloride, 0.001 M EDTA, pH 7.6). Concentration was determined at A260 using nanodrop ND-1000. DNA was prepared from cell line WM3622. 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.
