Human Caucasian malignant melanoma

Established from a malignant melanoma of a 31 year old male Caucasian. The cells produce melanin for up to 50 population doublings. The Y chromosome could not be detected in this cell line by short tandem repeat (STR)-PCR analysis when tested at ECACC. It is a known phenomenon that due to the increased genetic instability of cancer cell lines the Y chromosome can be rearranged or lost resulting in lack of detection. The cell line is identical to the source provided by the depositor based on the STR-PCR analysis.
