皮升大小的单分散液滴内的细胞的封装提供了新的手段,以进行定量生物学研究的单细胞基础上的大细胞群体。由于随机细胞加载,每滴细胞数量的可变性是这些技术的主要障碍。我们克服了这个限制,均匀间隔细胞,因为他们在一个高纵横比的微通道内旅行;细胞进入液滴生成器的频率下降形成。
Encapsulation of cells within picolitre-size monodisperse drops provides new means to perform quantitative biological studies on a single-cell basis for large cell populations. Variability in the number of cells per drop due to stochastic cell loading is a major barrier to these techniques. We overcome this limitation by evenly spacing cells as they travel within a high aspect-ratio microchannel; cells enter the drop generator with the frequency of drop formation.
