Database of Cross-contaminated or Misidentified Cell Lines
This database lists cell lines that are currently known to be cross-contaminated or misidentified. The database was originally developed by Amanda Capes-Davis and Ian Freshney, and published in 2010. It is now curated by the International Cell Line Authentication Committee.

About this Dataset
- The database currently lists 475 cell lines.
- 438 cell lines are misidentified with no known authentic stock, and are listed in Table 1.
- 37 cell lines were initially thought to be misidentified but authentic stock has since been found. These 37 cell lines are listed separately in Table 2.
- Cell lines that legitimately come from the same donor are excluded from the database – for example, if one cell line is known to be derived from another.
- 44 cell lines do not correspond to the original donor, but the contaminant is unknown. 43 cell lines come from a different species.
- 138 different contaminants are listed. The commonest is HeLa, with 113 entries (24%).
