产品描述

单细胞牵张拉伸压缩形变与机械力特性测试分析系统

——基于微流控技术的单细胞机械力特性精准、高通量表征 
Single cell mechanics - the easy way 
 
背景: 
单细胞水平的机械力特性表征,可以有效阐明细胞的功能和状态,揭示细胞的单体差异性,对于细胞的分化和病理研究,以及**的早期临床诊断和**具有非常重要的意义。 该系统基于微流控芯片的方式更适合单细胞样本的微环境**控制、高通量定向操纵及多参数非特异性检测。 
简介: 
该单细胞高通量牵张与力学特性测试分析系统,是****台用来高通量测量、分析单个悬浮细胞形变的设备。用来可视化研究讨论细胞力学性质与其功能之间的关系 该系统可以安装在任何相位差显微镜上的模块。温度稳定和激光**。 
单细胞牵张拉伸压缩形变与机械力特性测试分析系统  

 

系统亮点特性: 
)可大量表征单细胞机械力特性、操作简便、样品消耗量小 
该系统的微流控芯片具有与细胞直径良好相符性的微纳米级腔道,并能实现对微流体的**控制,使其尤其适合单细胞机械特性研究分析,该微流控的高通量技术便于大量表征单细胞机械力特性、操作简便、样品消耗量小、集成和微型化程度高等优点,且在分析过程中单细胞悬浮高速流经检测区域,该连续流动态检测的特性*大提高了系统的通量。 
2)高速对单个细胞进行形变,并进行机械特性高速表征,单细胞高通量流变 
利用两素未聚焦光进行单细胞形变,并通过图形化微柱基地表征细胞的力特性,高速有效分析单细胞水平的机械特性, 高达300个细胞/小时. 
3)非机械接触、无标记进行细胞捕捉和拉伸,确保细胞**与细胞损伤*小化(Contact-free cell deformation)
利用光延伸器技术测试细胞机械特性能时,在非机械接触情况下细胞进行捕捉和拉伸,且不需要对激光进行聚焦,能实现细胞损伤*小化。优于AFM(原子力显微镜)和光镊 
4)将光延伸器**性与微流控高通量**相结合,细胞机械特性测试分析**而且高效 
采用2个微流道来输送细胞,使两条光纤垂直分布于通道两侧并严格对准? ,单细胞随流体进入检测区域时,首先采用功率较低的光速捕获细胞,然后增加光速的功率使细胞发生形变。通过对细胞变形能力的分析,不仅能区分病变细胞和正常细胞,而且可以用于辨别转型特性和非转移特性的癌细胞。 
5)自动化测量单细胞力属性和成像记录细胞形变记录 
对应于用户定义的拉伸模式,细胞被自动传送到测量区域由CellStretcher模块控制所有组件和自动测量细胞;细胞形变由系统CCD相机自动记录,并由CellEvaluator自动提取记录显微图像形变数据,CellReporter可视化统计分析表征参数。在光学拉伸加载运行实验中,科研学者可专注于阐述实验结果 
6)良好温控微环境罩
