Method 1
Nebraska Wesleyan University (NWU) Forensic Science Graduate
students in an Advanced Bloodstain Pattern Analysis seminar were
provided two HemaScein TM kits. They were given directions to
prepare exemplars with human blood dilutions, commercial stage
blood products, red food coloring, Clorox, and red poster paint.
They were assigned to prepare the fluorescein product via the kit kit
instructions, apply the fluorescin to their exemplars, and document document
and observe the reactions on the exemplar. They were to test
known whole blood using the HemaTrace components of the kit.
The exemplars were pieces of white “sheetrock sheetrock” that had been used
in bloodstain research involving fly artifacts. The exemplar came came
to
the students with old human blood and fly artifacts.
