Detecting and locating semen stains is addressed by identifying the associated acid phosphatase activity of semen. The recovery of semen stains is critical as it can, via DNA testing, address the possible source(s) of the semen and may aid in the interpretation of a case. The purpose of these experiments, carried out on behalf of the Body Fluids Forum, was to consider whether wetting the test paper alone or wetting the semen stained fabric and the test paper affected the detection and location of the semen stains on various fabric types, or the subsequent recovery of spermatozoa from these fabrics. It became evident that the preferred approach varied depending on the fabric type being tested but that more often than not, wetting both the fabric and the test paper had a detrimental effect on the recovery of spermatozoa.
通过识别精液相关的酸性磷酸酶活性来检测和定位精液污渍。精液污渍的提取至关重要,因为通过DNA检测,它可以确定精液的可能来源,并有助于案件的解读。这些代表体液论坛进行的实验的目的是考虑仅湿润试纸还是同时湿润沾有精液的织物和试纸,是否会影响在各种织物类型上对精液污渍的检测和定位,或者随后从这些织物中提取精子。很明显,首选方法因所测试的织物类型而异,但通常情况下,同时湿润织物和试纸对精子提取有不利影响。
