Magle Life Sciences™ Papier médico-légal de détection de l’amylase dans la salive Phadebas™
Used for presumptive testing of suspicious stains. Phadebas™ Saliva Amylase-detection Forensic Paper is based on the Phadebas Amylase Test tablets but follows a separate method developed by the Forensic Biology labs.
Biodegradable starch microspheres (DSM) is Magle's core proprietary technology.
DSM is also used in diagnostic assays for the quantification of amylase and as a screening method in forensic biology.
The Phadebas® Amylase Test is used for both qualitative and quantitative assessment of the alpha-Amylase enzyme. The test consists of starch tablets in which a blue dye has been chemically bound to the starch. Alpha-Amylase degrades starch, thereby releasing the blue dye. The enzyme activity of the tested sample is given by measuring the absorbance of the blue solution. Phadebas® is used in a wide range of applications from diagnosis of pancreatitis to quality control tests for food and beverages and as a method for detecting saliva in forensic investigations.
Phadebas® Forensic papers are used in a Press test for detecting and identifying hidden saliva stains. The test is capable of locating saliva deposits on any item or surface, say for example a piece of clothing or a bed sheet. A major strength is the test's ability to detect stains regardless of the type of fabric or material onto which the saliva was originally deposited. The test is highly selective, the reason being that amylase activity in saliva is typically several orders of magnitude higher than in other body fluids.
