The detection of the enzyme acid phosphatase applies to cases of sexual crimes against dignity and fraud in samples of bovine semen, horse, etc...
Every two hours is recorded a case of sexual assault in the state of Rio de Janeiro.
The ISP-SESEG recorded from 2008 to 2012 an increase of 50% in cases of sexual assault in the state of Rio de Janeiro, the numbers may be related to an escalation of violence or a rise in complaints.
The semen contains high concentrations of the enzyme acid phosphatase in their composition, thus applying the reagent Phenolphthalein Bisphosphate Tetrasodium on a suspicious stain the material to be analyzed, if disclosed a reddish stand before the presence of this enzyme.
Qualitative tests on tissues and wet options presented in (c) and (d) are reagents synthesized in LASAPE. With the higher performance than the imported , with the possibility of staining broader spectrum by adding developing solution, these reagents can protrude on red fabrics and near red color.
In cases of sexual assault followed by killing the detection of the enzyme acid phosphatase, can be accomplished using the reagent phenolphthalein Bisphosphate Tetrasodium in macerated larvae of Chrysomya albiceps spp. obtained from decomposing bodies.
