BLUEBLOOD is applicable for searching and discovering latent bloodstains on various surfaces, as well as for fixing and enhancing the development of blood fingerprints, blood footprints, etc. The reagent uses water as a solvent, contains no harmful substances for health. Upon contact with blood, it instantly changes from colorless to a distinctive blue that is highly visible to the naked eye. The color does not fade, and the solidifying formula ensures that the background is not blurred and the contours are clear. The false-positive inhibitor ensures high specificity and minimal false positives. Moreover, the reagent has passed DNA testing and does not destroy DNA.
Compared to the tetramethylbenzidine, the Blueblood reagent has the following advantages:
- Non-toxic and safe
- Highly specific
- Highly visible
- Capable of solidifying bloodstains
- Does not destroy DNA
