Note that there are several types of synthetic blood available. Theater blood is designed to look like real blood, but is unsuitable for our purposes. Synthetic blood designed for use in spatterpattern analysis is also unsuitable. ) Buffers, DNA loading and running The FK01 Forensic Science Kit includes a 6X concentrate of DNA loading buffer and a 20X concentrate of DNA running buffer. If you don’t have the kit, you can make up these buffers yourself or purchase them from forensic supply vendors or general lab supply vendors.
