The following Luminol method is my favourite and works well with the chemicals I worked with.
Luminol Solution:
Dissolve 4g of Sodium Carbonate in 500mL of Distilled Water (This brings the pH to approx 11 which I found to be optimum for dissolving Luminol).
Add 0.2g of Luminol and dissolve.
Add 25g of Ammonium Carbonate and 0.2g of Ammonium Carbonate (This re-Buffers to pH of around 10.5, I found this to be optimum for this reaction).
Dilute to 1L with distilled Water. (Use only 25 mL at a time as this makes the solution last for a few experiments).
Oxidising Solution:
~ With K[sub]3[/sub]FeCN[sub]6[/sub] (Potassium Ferricyanide)
0.76g of K[sub]3[/sub]FeCN[sub]6[/sub]
Dissolve in 25mL of 5% H[sub]2[/sub]O[sub]2[/sub].
Mix these solutions together to begin the reaction
This reaction here will produce a lasting glow for more than 50 seconds.
I hope this adds to everyone's repertoire of Luminol Experimentation.

For all those
doing the Forensics Prac
ARE YOU USING BLOOD -please ref CSIS
therefore is Luminol necessary
an alternative is red jelly and ph adjust then use an indicator

Just to Re-iterate
Just to re-iterate what juliem has mentioned,
These pracs rely on the Oxidising solution in combination with the Luminol to produce the Chemiluminescence reaction.
All of which are indicated in each Method I have outlined and there is no need for any blood product. These reactions are purely Chemical!
Hope this avoids any confusion..
