LselectinPNAdInteractionsunderFlowConditions.
PurposeThe main purpose of the flow chamber assay is to visualize and measure interactions between flowing cells expressing a given adhesion molecule on their surface, and their receptor, either directly coated on the flow chamber lower wall or expressed on a cell monolayer.The present protocol will focus on the interactions between L-selectin expressed on neutrophils and PNAd coated onto the plastic surface.For neut......阅读全文

流式细胞仪(Flow－Cytometry):镏金岁月50年
自从50年前诞生至今，流式细胞仪（Flow cytometry）一直并仍然是无以伦比的高通量、高内涵的单细胞分析技术。 2015年11月，是流式细胞仪诞生50周年之时。人们可能会想象，一种如此长时间以前发明的技术应该到今天会是彻底地不同于当年，但是事实不然，它的基础原理与结构几乎没有什么改变，

氧气供应对处于浸浴状态的海马网络活动的重要性
过去对脑切片的研究， 对神经元和突触的基本特征方面已取得了丰富资料。但在完整的脑，进行中的的网络活动可能会严重影响这些特征。虽然，生理上更接近现实的网络活动模式已能在保存于界面型培养容器中的脑切片中成功地诱导出来，但此类资料却难以在浸浴型培养容器中取得，而浸浴型容器却能提供更好的实验优势，包
