“Photography has always been an issue with luminol and similar products due to the need for long time exposures and continuous application to sustain the light emission. The constant needed to apply luminol products often causes running of the latent blood materials and loss of detail. Heamscein™ offers a distinct advantage for capturing image detail by lessening the problem of overspray and maintaining a long lasting light emission”Click here to request a copy of this study

 

Hemascein® detects latent bloodstains using novel fluorescein C20H10Na2O5 as an active component in the formulation. The aqueous formulation of Hemascein® reveals latent bloodstains based on the peroxidase-reduction of a reduced colorless reagent sprayed over the targeted area. An area suspected of containing latent bloodstains is sprayed with Hemascein® using ABASpray™. The Hemascein® reagent reduced with hydrogen peroxide (colorless) is immediately oxidized to fluorescin by the presence of blood-associated proteins and will fluoresce when excited by a light source between 415 and 480 nm. Once latent bloodstains are located, they can be tested at the crime scene if they are of human origin with the help of Hematrace®, a 10-minute immunochromatographic test. The evidence can then be swabbed and transported for further DNA analysis.   Sensitivity in detecting latent bloodstains  2 to 5 times when compared to other tools in use DNA recovery of diluted blood  Yes Recovers finer detail Yes Longevity, time for documentation Highest when compared to other tools in use Stability 7 yrs (Room Temperature) Safety Fluorescein is routinely used in humans Identify if human origin Yes (Hematrace®) Formulation Fluorescein containing formulation   (aqueous) Requires dark room and eyes to adjust to darkness No     “HemaScein® addresses the issue of health hazards and liability. A luminol application created substantial liability issue in a claim to purchase  a vehicle and the payment of medical bills of an adult and children who were affected by the residue luminol left behind in the application to a vehicle interior.  ….investigators reported burning to their hands and face after using luminol……. private citizens filed a claim and received compensation directly due to health issues arising from the use of luminol. … the jurisdiction of record bought motor vehicles that had been processed with luminol.   Hemascein® does not present this liability issue of a residual hazardous material left behind at the scene. The author over the past 11 years in using fluorescein has never received a complaint from a citizen or investigator of direct health issues."– Sergeant Larry Barksdale, Lincoln Police Dept., USA Click here to request a copy of this study     Kit Contents and Ordering Info Watch real case videos Download and print this info Request More Product Information
