Cat STRs

As with human DNA, genetic material obtained from cats contains short tandem repeat (STR) markers that are highly variable among individuals and thus useful in differentiating between animals. As part of a collaboration with the National Institute of Cancer's Laboratory of Genomic Diversity with funding from the National Institute of Justice, NIST helped develop a STR multiplex with a number of cat STR loci. Below is some helpful information developed as part of this collaboration on cat STRs.
