WM88 Purified RNA

Total RNA was extracted and purified from cells using RNA isolation & purification kit according to manufacturers instructions. The RNA was diluted to 200 ng/µL in RNase free water. Concentration was determined at A260 using nanodrop ND-1000. Total RNA was prepared from cell line WM88. WM88 is a tumorigenic primary melanoma cell line with competence for metastasis. These cells display melanocytic morphology in culture. This cell line was established from a metastatic site in a male patient with level III superficial spreading melanoma with tumor thickness of 0.92. This cell line contains the V600E (Val600Glu) mutation at codon 600 in the BRAF gene. This mutation occurs within the activation segment of the kinase domain and causes constitutively active kinase activity and activation of MEK and ERK signaling pathway. The cells are wild type for PTEN, N-ras, c-KIT and CDK4. WM88 cells produce xenograft tumors when injected into immunocompromised mice.
