ABSTRACT: The YFiler Platinum Casework PCR Amplification Kit is a 6-dye multiplex assay that simultaneously amplifies a set of 38 male-specific, Y-chromosome Short Tandem Repeat (YSTR) markers (DYS576, DYS389I, DYS635, DYS389II, DYS627, DYS549, DYS593, DYS645, DYS460, DYS458, DYS19, YGATAH4, DYS448, DYS391, DYS557, DYS522, DYS456, DYS390, DYS438, DYS392, DYS518, DYS444, DYS533, DYS570, DYS437, DYS385, DYS449, DYS643, DYS596, DYS393, DYS439, DYS481, DYF387S1, DYS527, DYS447), three insertion/deletion polymorphic markers (Yindels: rs771783753, rs759551978, rs199815934), and an internal quality control (IQC) system. When compared to the YFiler Platinum PCR Amplification kit for database samples, YFiler Platinum Casework kit was developed to include an improved Primer Mix incorporating a brighter TED dy
