1项目基本情况脱落细胞提取是目前法医DNA检验中的难点和重点,为了解决传统提取方法和工具提取效率低、适用范围窄、操作手法复杂、基层推广难度大的困局,项目组创新研发了一种可适用各种特殊形状载体的脱落细胞“百变”粘取器。“百变”粘取器具有三大创新亮点:一是适用范围广,提取效率高,“百变”粘取器的弹性手柄具有很好的形变能力,适用于现场各种凹凸不平、弯曲的载体表面,超强的粘附能力能够有效富集粗糙、渗透性载体上的脱落细胞。
1 The basic conditions of the project Exfoliated cell extraction is the current forensic DNA testing of the difficulties and priorities, in order to solve the traditional extraction methods and tools to extract low efficiency, narrow scope of application, complex manipulation practices, grass-roots promotion difficult dilemma, the project team innovative research and development A variety of special shapes can be applied to the exfoliated cells carrier “Variety” sticky. “Variety ” Sticker has three innovative highlights: First, a wide range of applications, extraction efficiency, “Variety ” Ejector flexible handle with good deformation ability for a variety of on-site irregularities , Curved support surface, super adhesion ability can effectively enrich the exfoliative cells on the rough, permeable carrier.
