Abstract

Species identification of cell lines and detection of cross-contamination are crucial for scientific research accuracy and reproducibility. Whereas short tandem repeat profiling offers a solution for a limited number of species, primarily human and mouse, the standard method for species identification of cell lines is enzyme polymorphism. Isoezymology, however, has its own drawbacks; it is cumbersome and the data interpretation is often difficult. Furthermore, the detection sensitivity for cross-contamination is low; it requires large amounts of the contaminant present and cross-contamination within closely related species may go undetected. In this paper, we describe a two-pronged molecular approach that addresses these issues by targeting the mitochondrial genome. First, we developed a multiplex PCR-based assay to rapidly identify the most common cell culture species and quickly detect cross-contaminations among these species. Second, for speciation and identification of a wider variety of cell lines, we amplified and sequenced a 648-bp region, often described as the "barcode region" by using a universal primer mix targeted at conserved sequences of the cytochrome C oxidase I gene (COI). This method was challenged with a panel of 67 cell lines from 45 diverse species. Implementation of these assays will accurately determine the species of cell lines and will reduce the problems of misidentification and cross-contamination that plague research efforts.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
