Conclusion (cont.) Current literature does not indicate destruction of DNA with application of fluorescin nor the amounts of hydrogen peroxide needed for the fluorescein reaction. The Hemascein formulation should present no threat to recovery of DNA. <strong>HemaScein</strong> TM addresses the issue of health hazards and liability with the fluorescein product as the primary blood detection product. The fine spray should reduce aesthetic and clean-up clean up issues when spraying the interior of vehicles. <strong>HemaScein</strong> TM sprayers worked as designed. In some cases students had to spray several times to get a reaction started. The sprayers sprayers effectively addressed the issues of over spraying of fluorescin solutions causing running of the bloodstains and over spraying of of fluorescin solutions causing background interference.
Epilogue: Author’s Author s Observations Fluorescein discovery and presumptive testing has an experiential experiential application curve. For those used to using luminol and luminol based products the immediacy immediacy and light intensity associated with fluorescein is not as great. It takes some getting used to knowing what you should see. Once you become accustomed to what to look for, fluorescein becomes a workable product for discovery of latent blood either singularly or as an extension of patent stains. Fluorescin does not react quickly with whole blood. This is a positive positive aspect for crime scene investigators. That is, if it is observable why test for latent materials? If there is a need for enhancement, use one of the protein stains. Fluorescein Fluorescein and luminol products are for what you cannot see. (Fluorescein is the material material added to make the solution. Fluorescin is the material in solution. Fluorescin goes goes back to fluorescein when reacting with blood components). Real time or very short time exposures are possible with fluorescein. fluorescein. This is due to the long reaction time and the use of the alternate light source. source. Photography has always been an issue with luminol and similar products due to the the need for long time exposures and continuous application to sustain the light emission. emission. The constant needed to apply luminol products often causes running of the latent blood blood materials and loss of detail. Heamscein offers a distinct advantage for capturing capturing image detail by lessening the problem of overspray and maintaining a long lasting lasting light emission.
