Sigma-Aldrich Product Name COLO 857, 93051120 biological source human lymph growth mode Adherent

Human melanoma

Derived from a right axilla lymph node of a 43 year old male with melanoma. The biopsy material was obtained post chemotherapy.COLO 839 (Sigma Catalogue number 93051119), COLO 858 (Sigma Catalogue number 93052613) and COLO 857 (Sigma Catalogue number 93051120) were all derived from the same 43 year-old male patient with malignant melanoma (see references below). This has been confirmed by STR profiling. 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.
