Acid Fuchsin (Hungarian Red) with fixative, AqueousSKU: 1507
Numerous methods of staining are used to develop or enhance blood-contaminated latent prints. These methods depend on staining the protein components of blood to form a more visible impression, commonly a dark blue or black. Among these methods are Amido Black, LeucoCrystal Violet, Coomassie Blue, and Acid Fuchsin.
Acid Fuchsin, also known as Hungarian Red, is an excellent stain for the enhancement of bloody fingerprints or footwear impressions. Enhanced impressions can be caused to fluoresce with an ALS or laser. Stained impressions can be lifted with a white gelatin lifter, excited at 515-560 nm and photographed with a red barrier filter.
