使用层流洗涤可以改善从研究到分析开发再到制造质量控制的数据。层流清洗技术可为细胞和基因治疗应用提供以下功能:
变异系数更低
提高实验在不同操作者、时间和地点中的可重复性
减少手动操作时间
减少工作总时长

细胞治疗过程
流式细胞术依赖于数据一致性和重现性来产生生物学相关信息。然而,传统的样品制备方法往往无法满足这些关键标准。我们如何应对这一挑战?
在使用传统离心方案的细胞治疗过程中,稀有细胞群的清洗分离和保留被证明是一个问题,这会导致显著的机械应力、活力降低和靶细胞的保留率低。这在处理gamma-delta T细胞等细胞细胞类型时尤其成问题,这些细胞类型往往具有较低的起始细胞数量和高度的可变性。因此,能够清楚地分辨这些群体以确保为正确的患者提供最佳的细胞治疗至关重要。
HT2000系统经过全新改进,带来便于菜单选择的触摸屏幕,以及用于自动启动和关闭序列的缓冲液交换器,可作为独立平台或作为全自动解决方案的一部分使用的AUTO1000系统。
Laminar Wash™ HT2000系统为箱规不一致的离心过程及其相关的洗涤步骤提供了一种行之有效的替代方案。它确保不同操作者进行可重复的自动清洗,以及类似或改进的细胞保留和活力。通过消除对板轻弹的需要,它大大降低了交叉污染和对科学家的生物安全危害的风险,骑在保持细胞状态的同时有效去除细胞碎片的标志性优势,有助于更清洁地分离稀有细胞群。越来越多的实验室在其工作流程中采用了Laminar Wash™技术,并证明了这些优势。
“The Laminar Wash’s performance allows us to get very tight control over populations with very tight CV’s largely due to the fact of the clear separations between populations. The maintained ability to detect rare populations is important as we detect the next round of cell therapy products.”

用于制备用于流式细胞术分析的单细胞悬液的免疫染色工作流程的比较。层流洗涤技术在洗涤方面同样有效,但无需使用离心机。
变异系数更低
提高实验在不同操作者、时间和地点中的可重复性
减少手动操作时间
减少工作总时长
与多个离心步骤相比,使用层流洗涤的一步洗涤最大限度地减少了细胞扰动,增加了单核细胞和中性粒细胞群的保留。
