Our Leucocrystal Violet Aqueous Protein Stain (LCV) is commonly used to enhance blood stained fingerprints and footwear impressions. Leucocrystal Violet will not enhance a print composed solely of normal latent print residues, so it is used only in cases with blood-contaminated impressions. LCV is nearly colourless when first mixed, but is oxidized by the catalytic action of hemoglobin in the bloodstain, and will convert to a blue-coloured solution, which will then stain the bloodstain.
