SBI公司外泌体定量检测试剂盒选择指南
EXOCET外泌体定量试剂盒设计为已知在外泌体中富集的乙酰辅酶A乙酰胆碱酯酶(AChE)活性的直接测量(Savina,2002和Gupta,2007)。 SBI还通过质谱研究和Western印迹证实AChE高度富集来自血清,干细胞,癌细胞系和MSC外来体的外泌体。 EXOCET测定与来自所有测试的哺乳动物物种(人,小鼠,大鼠)的外泌体相容,并与使用ExoQuick,ExoQuick-TC,超速离心,免疫亲和纯化和色谱法分离的外泌体兼容。 EXOCET外来体定量系统是在OD405比色法测定酶活性。该测定是快速的,从开始到完成仅20分钟并且高度定量。已通过NanoSight分析校准到分离的外泌体的标准曲线包括在试剂盒中,其能够测量样品中外泌体的数目。 EXOCET96A-1试剂盒包含所有必需的试剂和一个96孔反应板。
使用标准ExoQuick和ExoQuick-TC试剂从人血清(0.5mL)或MDA-MB-231培养基(10mL)中分离外泌体。 将外泌体沉淀物重悬浮并测量蛋白质浓度(约108个外泌体,2ug / ul)。 使用EXOCET温和裂解溶液裂解外泌体,以保持外来体AChE酶的酶活性。 使用已知数目的外泌体(通过NanoSight测量)并用试剂盒中提供的重组AChE酶标准溶液校准来产生标准曲线。

Supporting Data
The standard curve for ExoELISA-ULTRA CD81 shows robust linearity down to ~4 x 109 exosomes.
Figure 1. ExoELISA-ULTRA CD81 standard curve shows robust linearity down to ~4 x 109 exosomes. OD450nm values of commonly used samples (e.g. human serum, HEK293T, and MCF7 breast cancer exosomes – in large colored dots) fall well within the standard curve for the assay.
