Commercially Available STR Multiplex Kits

Kits from commercial sources are now predominantly used by labs around the world for their ease of use and high discriminatory power.

Explanation of STR Multiplexes:  

The desire to gain more information from a sample, coupled with the need to limit consumption of a DNA sample where its availability may be limited (such as evidence from a crime scene) has led to the co-amplification and typing of multiple STR systems. Multiplex PCR, which involves adding more than one set of PCR primers to the reaction in order to target multiple locations throughout the genome, is an ideal technique for DNA typing because the probability of identical alleles in two individuals decreases with an increase in the number of polymorphic loci examined. The advent of fluorescent labeling of the PCR primers permits the multiplexing of STR loci which may have alleles that fall in the same size range by labeling the overlapping loci with different colored fluorescent dyes that can then be resolved spectrally.
