ObjectiveTo compare ho memade and commercial g oldlabeled strips of antihuman seminal protein of P30 to explore and d efine their availability on forensic examination. Method Titers and sensitivities were detected with the antigen of a mixture of seminal fluid from 6 people and the purified human prostate specific antigen, whereas sp ecificities were with feminine vaginal secretions, human sera, human saliva and human colostrums, and the power identifying human seminal stains was established with old human seminal stains and blinddrawn material evidences. R esultsFor the titers and sensitivities the homemade strip of gold labeled antihuman seminal protein of P30 was equal to the better ones of those commercial, but on specificities the homemade one is at least eq ual o r even better than the commercial ones, having no reactions against the tested s ubstances used for the establishment of specificity, however the commercial ones were most of all having nonspecific reactions. Conclusion It is very important to select the strips adaptable to the requirements of f orensic examination, so there exists a necessity to define their forensic availa bility for commercial strips before use.
