提供了组织结合酶法和半自动机械解离以产生用于下游分析(例如流式细胞术)的单细胞悬浮液的通用方案。包括为该协议开发的低成本机械装置的制造、组装和操作说明。

我们的实验室开发纳米颗粒作为研究生物屏障的工具,并克服粘膜表面的这些屏障,以改善药物递送和免疫治疗。最显着的发展之一是辉瑞、BioNTech 和 Moderna 的 COVID-19 疫苗,它们使用脂质纳米颗粒配方递送 mRNA 用于疫苗接种。目前有很多正在进行的努力来改进免疫疗法,如使用纳米颗粒的疫苗和癌症治疗,因为这些制剂可以改善对免疫细胞的靶向递送并减少免疫疗法的全身副作用。

单细胞分析是生物医学研究中免疫学的重要组成部分,最常见的技术之一是流式细胞术。从目标组织中进行此类细胞分离需要可靠的组织解离。在不影响质量和准确性的情况下使实验室研究更容易进行可能具有挑战性。

自动化流程使技术和劳动密集型步骤更容易学习,并允许受训者在不影响结果可靠性的情况下获得进行更复杂分析的经验。该协议和随附设备设计的主要优点是其可定制性和成本效益。能够同时处理多达 12 个组织,从而缩短了处理时间。

这种低成本的替代方案使这项技术在资源匮乏的研究环境中更容易获得。
