Blood Identification and Reagent

Naphthalene Blue Black. Amido Black is a dye which stains protein present in blood to give a blue-black product. It will not detect the normal constituents of latent fingerprints, and therefore, must be used in sequence with other techniques when...

Coomassie Blue enhances latent prints contaminated with blood on porous and non-porous surfaces, but will not develop a normal perspiration-based print. Application can be repeated until maximum contrast is achieved. Gather physiological samples and...

An effective protein stain used to develop and enhance bloody fingerprints or footprints deposited on non-porous surfaces. Various protein stains, such as amido black, etc., can be used after processing with LCV. Cyanoacrylate fuming may be...

An intense BLUE-GREEN color reaction in 3 seconds is presumptive evidence that blood is present. Leucomalachite green has long been a favorite of field investigators because of its high sensitivity (1:300,000). Set of six tests with contact paper.

Luminol reagent requires a darkened area for observation. This is the ideal reagent for “aged” or invisible blood stains. In fact, the older the stain, the brighter the reaction. Luminol is one of the most sensitive presumptive field test for blood...

A remarkable product that features luminol which will show tracings, even after blood has been cleaned up. You spray it on, and like magic, microscopic amounts of blood tracings flash an eerie blue glow. This is the answer when nothing else works. A...
