A radial gel diffusion method utilizing urease and bromthymol blue has been developed for urine stain identification. Urea, present in urine in relatively high concentrations, can be detected from urine stain extracts. This technique provides both qualitative and quantitative results, and is sensitive enough to detect 0.078 micrograms/microliter of urea.
一种利用脲酶和溴百里酚蓝的径向凝胶扩散法已被开发用于尿渍鉴定。尿液中尿素浓度相对较高，可从尿渍提取物中检测到尿素。该技术可提供定性和定量结果，灵敏度足以检测出0.078微克/微升的尿素。
