WM852 Non-Viable Cell Pellet

Cells were grown sub-confluent to approximately (2x10^6) cells in Tumor specialized media and then trypsinized. Cells were harvested and cell pellets were flash frozen and stored at -80°C. Non-viable cell pellet was generated from cell line WM852. WM852 is a metastaic melanoma cell line with epithelial morphology. This cell line was established from the metastatic site (abdomen) in a 63-year -old male. This cell line contains a Q61R mutation at position 61 in the N-RAS gene. The Q61R is the most common NRAS mutation found in melanoma that is thought to occur due to UV and radiation exposure. This mutation leads to production of a constitutively active N-RAS protein that directs cells to grow and divide constantly. This cell line also expresses PTEN loss of function including hemizygous deletion and is wild type for BRAF, c-KIT and CDK4. WM852 cells produce xenograft tumors when injected into immunocompromised mice.
