WM3928 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 WM3928. WM3928 is a human metastatic melanoma cell line that displays a mesenchymal morphology. This cell line was established from a left inguinal lymph node metastatic site of a patient. This cell line contains the PTEN Y177X substitution mutation. Y177 is a phosphorylation site in PTEN and mutation of Y177 leads to misregulation of PTEN function. This cell line contains wild type BRAF, N-RAS, c-KIT and CDK4 genes. WM3928 cells produce xenograft tumors when injected into immunocompromised mice.
