Cross-contamination of cell lines is a highly relevant and pervasive problem. The analysis of short tandem repeats (STR) is a simple and commercially available technique to authenticate cell lines for more than two decades. At present, STR multiple amplification kits have been developed up to 21 loci while the current STR databases only provide 9-loci STR profiles. Here, we compared the advantages of 21-loci STR methodology using the same algorithm as 9-loci method. The 21-loci method reduced the uncertainty ratio for authentication
