STR multiplex system

An STR multiplex system is used to identify specific <a href="/facts/Microsatellite/SwfHbeXG">short tandem repeats</a> (STRs). STR <a href="/facts/Polymorphism_(biology)/lf32kgfV">polymorphisms</a> are <a href="/facts/Genetic_marker/pRshdIBz">genetic markers</a> that may be used to identify a <a href="/facts/DNA_sequence/hsPsNCQW">DNA sequence</a>.
The <a href="/facts/FBI/UY93jwX6">FBI</a> analyses 13 specific STR <a href="/facts/Locus_(genetics)/JcIT8wLm">loci</a> for their database. These may be used in many areas of genetics in addition to their forensic uses.
One can think of a STR multiplex system as a collection of specific STRs which are positionally conserved on a target genome. Hence these can be used as markers. A number of different STRs along with their loci in a particular genome can be used for <a href="/facts/Genotyping/GRyXkRcn">genotyping</a>. 
For example, the STR multiplex system AmpFlSTR Profiler Plus which analyses nine different STRs (3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820) plus <a href="/facts/Amelogenin/Re03SL3m">Amelogenin</a> for sex determination is used for human identification purposes.
