Amido Black is a protein dye sensitive to the properties in blood. It can be used to enhance or develop blood-contaminated latent prints. Bloody latent prints, even those not visible to the naked eye, may be developed on porous or nonporous surfaces, such as cadavers, wood, or paper. You can purchase Amido Black powder (25 gram bottle) and mix it in Glacial Acetic Acid and Methanol. For more information, view our Technical Note. Or you can purchase a pre-mixed Aqueous Amido Black.

Shelf-life of Amido Black Powder: indefinite unless wetted. The working solution becomes contaminated quickly upon use. It is best to mix fresh solution if contaminated.

Aqueous Amido Black

Aqueous Amido Black is a pre-mixed Amido Black solution. It can be used to enhance or develop blood-contaminated latent prints. Bloody latent prints, even those not visible to the naked eye, may be developed on porous or nonporous surfaces, such as cadavers, wood, or paper. Since this solution is aqueous (mixed with water), it is a bit safer to use and you do not have to pre-soak the various objects in Methanol as in the procedure for the mixed solution of the Amido Black powder above.

Shelf-life of Aqueous Amido Black: one year if not subjected to extreme high or low temperatures. Do not refrigerate.
