Abstract

We have designed and evaluated a series of class-specific (Aves), order-specific (Rodentia), and species-specific (equine, canine, feline, rat, hamster, guinea pig, and rabbit) polymerase chain reaction (PCR)-based assays for the identification and quantitation of DNA using amplification of genome-specific short and long interspersed elements. Using SYBR Green-based detection, the minimum effective quantitation levels of the assays ranged from 0.1 ng to 0.1 pg of starting DNA template. Background cross-amplification with DNA templates derived from sixteen other species was negligible prior to 30 cycles of PCR. The species-specificity of the PCR amplicons was further demonstrated by the ability of the assays to accurately detect known quantities of species-specific DNA from mixed (complex) sources. The 10 assays reported here will help facilitate the sensitive detection and quantitation of common domestic animal and bird species DNA from complex biomaterials. © 2003 Elsevier Inc.
