Edvotek Forensic Blood Typing

This objective of this experiment is to introduce students to some of the techniques used by forensics scientists for analysing blood. The students first check for the presence of blood typing using the phenolphthalein test. Then the students will apply the concept of blood type-based screening for potential suspect(s) present at a crime scene.

• Understand the chemistry and the biology behind blood analysis techniques
• Explore presumptive and confirmatory forensic tests
• Perform a Kastle-Meyer test to identify blood at the crime scene
• Perform a hemagglutination assays to determine suspects and crime scene blood types
• Group size: for 10 groups
• Time required: complete in 50 minutes
• Kit includes: instructions, control ABO simulated blood samples, simulated crime scene and suspect blood samples, anti-A and anti-B serums, blood detection stock solutions, transfer pipets, microtitre plates, tubes, filter paper, cotton swab
• All you need: 95-100% ethanol, marking pen, distilled water; optional: automatic micropipette 5-50µL
