and TPOX), a quality indicator system, and two sex-identification markers. Combined, the markers satisfy the requirements of the Chinese National autosomal DNA database as well as expanded CODIS (Combined DNA Index System). The VeriFiler Plus kit was developed with an improved Master Mix which incorporates the brighter TED™ dye, and accommodates a higher sample loading volume thus allowing for increased sensitivity and enabling maximum information recovery from challenging casework samples including touch, degraded, and inhibited samples. Here, we report the results of the developmental validation study which followed the SWGDAM (Scientific Working Group on DNA Analysis Methods) guidelines and includes data for PCR-based studies, sensitivity, species specificity, stability, precision, reproducibility and repeatability, concordance, stutter, DNA mixtures, and performance on mock casework samples. The results validate the multiplex design as well as demonstrate the kit's robustness, reliability, and suitability as an assay for human identification with casework DNA samples.
The Huaxia™ Platinum Kit for short tandem repeat (STR) amplification was designed to meet the needs of the rapidly growing Chinese forensic database. This PCR multiplex allows simultaneous amplification of the following autosomal loci: D3S1358,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
