autoMACS Pro产品说明
产品概述
   
autoMACS 是一个计算机控制的、可高速、高纯度、高回收率地分选多种类型细胞的全自动磁性细胞分选器。该仪器基本原理是MACS磁性细胞分选技术，自动进行细胞分选过程，包括预冲分选柱、样本摄取、洗脱阳性成分和阴性成分、冲洗、清洗和分选柱的维护。autoMACS Pro是一个开放的技术平台，广泛应用于细胞生物学、免疫学、肿瘤学、血液病学研究。
分选后细胞可直接用于后续实验：流式细胞术检测、分子生物学研究、回输给动物、以及功能研究，例如：肿瘤细胞的纯化、肿瘤疫苗研制、干细胞技术、免疫治疗的基础研究、异基因干细胞移植后的系特异性嵌合体分析、HLA分型和HIV研究。
 
技术原理：
MACS（磁性细胞分选技术）是一种广泛用来磁性分选多种细胞或者生物分子的技术。
• 基于抗体对抗原的特异性识别
 
• 磁性微珠直接或者间接偶联在抗体上，从而与细胞相连
 
• 在高强度、梯度磁场中达到细胞磁性分离的目的
 
与相应抗体偶联的MACS微珠可以磁性标记目的细胞，然后通过一个高强度和梯度的磁场，磁性标记细胞滞留在磁场中，而未标记细胞流出。去除磁场后，磁性标记细胞可以被洗脱下来。磁性标记和未磁性标记成分均可以回收利用。
 
autoMACS技术指标：
1、MACS微珠直径50nm。
2、使用MACS分选柱进行分选。
3、MACS微珠能降解，对细胞无毒性，分选后的细胞仍保持生理功能。
4、与流式细胞仪兼容，分选后细胞可以立即用于分析和后续实验。
5、分选后细胞纯度高、回收率和回收率高。
6、可直接用全血进行分选。
7、标本量从105到4X109，进样量从0.2ml到50ml。
8、内置12个预设分选程序，一机完成阳性分选、去除分选、低频细胞分选、抗原弱表达细胞分选。可以分选任何种类细胞。
