The goal of this research was the construction of a more cost effective method of utilizing the Applied Biosystems Identifiler Kit. Across the country there is a large backlog of samples that need to be processed in order to obtain a genetic profile. If these samples could be tested using a more cost effective method, more funding could be directed to other endeavors. Paternity testing, as well as some research endeavors could be conducted at a fraction of the cost, leaving resources for other projects or additional staff. Although it would be inadvisable to use this technique on forensic samples, the implications on paternity and research samples would be positive. This research attempted to design a nested PCR reaction and subsequently dilute the Applied Biosystems Primers in order to reduce the cost. The first step was to design new primers for the first round of PCR, followed by testing of those primers. The new primers then required optimization so that they all worked effectively together. After optimization was accomplished, the Identifiler primers were diluted until loci began dropping out of the genetic profile.
