    细胞微流体工作站VenaFlux (VenaFlux Platforms)是Cellix公司目前*受客户欢迎的一套系统,提供在活细胞水平上微流体活性筛选的完整解决方案。操作简单,分析效率高,可大大提高药品的开发和筛选效率。

    VenaFlux 系统是**个能进行连续流体细胞分析的半自动化微流体分析系统。配合使用Cellix生物芯片和细胞分析软件,VenaFlux 系统可检测粘附到微毛细管上的细胞,微毛细管中覆盖抗体或者培养有内皮细胞,模拟生理流动产生一定的剪切力。

    VenaFlux 系统操作简单,可减少耗时耗钱的动物模型实验,获得特异性强,准确性高,重复性好的结果。

    VenaFlux 流体细胞分析仪产品特点:

    ? 广泛使用于各种细胞悬浮液;

    ? 生物芯片可选择用光学显微镜做细节研究;

    ? 微流体泵可方便的控制流体剪切力在0.05到20dyne/cm2范围内;
