An improved method of group-specific component (Gc) typing was conducted electrophoretically on agarose gel. Individual bloodstains randomly collected from different individual donors over a five-year period at intervals of approximately one month were checked for Gc activity. Group-specific component was typed accurately in dried bloodstains stored at room temperature up to 43 months in age. From 100 different donors, bloodstains ranging in age from 38 to 43 months were tested by the methods described and 73% of the samples were interpretable for Gc.
采用在琼脂糖凝胶上进行电泳的方法对组特异性成分（Gc）分型进行了改进。对在五年期间每隔约一个月从不同个体供血者随机采集的个体血迹进行Gc活性检测。对于室温下保存长达43个月的干血迹，组特异性成分分型准确。按照所述方法对来自100名不同供血者、年龄在38至43个月的血迹进行检测，73%的样本可进行Gc分型解读。
