摘要:
Described herein are systems and methods for extending the dynamic range of assay methods and systems used for determining the concentration of analyte molecules or particles in a fluid sample. In some embodiments, a method comprises spatially segregating a plurality of analyte molecules in a fluid sample into a plurality of locations. At least a portion of the locations may be addressed to determine the percentage of said locations containing at least one analyte molecule. Based at least in part on the percentage, a measure of the concentration of analyte molecules in the fluid sample may be determined using an analog, intensity-based detection/analysis method/system and/or a digital detection/analysis method/system. In some cases, the assay may comprise the use of a plurality of capture objects.
摘要(中):
本文描述了用于扩展用于确定流体样品中分析物分子或颗粒的浓度的测定方法和系统的动态范围的系统和方法。 在一些实施方案中,一种方法包括将流体样品中的多个分析物分子空间分离成多个位置。 可以寻址至少一部分位置以确定包含至少一种分析物分子的所述位置的百分比。 至少部分地基于百分比,可以使用模拟,基于强度的检测/分析方法/系统和/或数字检测/分析方法/系统来确定流体样品中分析物分子的浓度的量度。 在一些情况下,测定可以包括使用多个捕获对象。
