Specifications include, but are not limited to: The Washington State Patrol (WSP) is an Agency of the State of Washington and is conducting a Request For Proposal (RFP) to solicit proposals from firms interested in providing a differential extraction chemistry that can provide robust extraction and efficient epithelial cell and sperm cell separation in forensic samples associated with sexual assault evidence. The chemistry must be suitable for automation on a chemistries-neutral liquid handling instrument, and produce lysates suitable for DNA purification that can subsequently be successfully quantitated and amplified using Promega products. Proposed chemistries put forward to WSP will be evaluated for potential use in a High-Throughput DNA laboratory.
