| Abstract: |
The National Institute of Standards and Technology (NIST) has provided a number of educational interlaboratory exercises to the forensic community. The recent NIST Mixed Stain Study #2 consisted of three separate sets of materials. Set 1) three stains on washed cotton sheeting, representing a sexual assault by an unknown assailant; a blood stain from the known female victim, a neat semen stain from a known suspect, and a mixed blood/semen stain of the above knowns plus an additional unknown semen specimen. Set 2) three stains on washed cotton sheeting, representing a sexual assault; a bloodstain from the known female victim, a neat semen stain from a known suspect, and a mixed blood/semen stain where the semen was different from the male reference. Set 3) five 20 L DNA TE buffer extracts in screw-capped vials with DNA concentrations stated to range from {approximately equal to} 0.2 to {approximately equal to} 20 ng/ L. Two of these Set 3 samples were, in fact, replicates. |
