目前,载体上脱落细胞提取的主要方法有:直接剪取、干湿拭子两步擦拭、脱落细胞富集器吸取、胶带粘取法等。本文针对衣物类载体上脱落细胞粘取器提取检材的效果进行考察,以期为相关鉴定提供参考。1实验方法1.1样本收集本实验室日常案件中的6个生物样本,包括:手套2只,口罩1个,帽子1只,内衣2件。样本均为案发现场提取,干燥新鲜,其中两只手套较脏。
At present, the main methods of exfoliated cell extraction on the carrier include: direct shearing, two-step wiping with wet and dry swab, exfoliation cell enrichment device and adhesive tape sticking method. This article examines the effect of extracting material from the exfoliated cell adhesion device on the clothing carrier to provide a reference for the related identification. EXPERIMENTAL METHODS 1.1 Sample Collection Six biological samples from our daily routine were collected, including two gloves, one mask, one hat and two underwear. Samples were taken from the scene of the accident, fresh and dry, two of which were dirty.
