Blood (Research project forensic science, just to make sure)

Post by TimeOfYourLife » Mon Sep 08, 2008 8:01 pm

Hey,
Short question from a highschooler but I don't trust most internet resources so I thought I'd ask..

For a project I need blood to have a reaction with blood (Luminol to prove the existence of removed blood), my project focusses on human blood and luminol reacts with the Fe 2+/3+ ions in the hemoglobin. To my belief there are some minor differences between human and animal blood, but these don't apply to the iron found in the hemoglobin thus allowing me to use animal blood instead of the human variant?

Am I correct here or am I going to have to find a human donor?

Thankyou for your time,

Henk

I think it reacts with any iron. The wikipedia article says it even reacts with copper.

if you're using it for the forensic purpose, then yes, you can still detect the trace amounts of blood by using animal blood. However, that does not prove your point, from the point of view of the scientific method, if you want to prove that luminol can be used to detect blood.
