Sigma-Aldrich Product Name SW 837, 91031104 biological source human colon growth mode Adherent

Human Caucasian rectum adenocarcinoma

Established from a Grade IV adenocarcinoma of the rectum of a 53 year old Caucasian male. The cells produce CEA and electron microscopy reveals brush borders. 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.
