Abstract: Element tags based on novel metal-polymer conjugates are provided for elemental analysis of analytes, including ICP-MS. A polymer backbone is functionalized to irreversibly bind metals that are selected prior to use by the user. The polymer is further functionalized to attach a linker which allows for attachment to antibodies or other affinity reagents. The polymer format allows attachment of many copies of a given isotope, which linearly improves sensitivity. The metal-polymer conjugate tags enable multiplexed assay in two formats: bulk assay, where the average biomarker distribution in the sample is diagnostic, and single cell format to distinguish a rare (for example a diseased) cell in a complex sample (for example, blood).

Abstract translation: 提供基于新型金属 - 聚合物共轭物的元件标签用于元素分析，包括ICP-MS。 聚合物主链被官能化以不可逆地结合在用户使用之前选择的金属。 该聚合物进一步官能化以连接允许附着于抗体或其它亲和试剂的接头。 聚合物形式允许附加许多拷贝的给定同位素，其线性地提高灵敏度。 金属 - 聚合物缀合物标签使得能够以两种形式进行多重测定：批量测定，其中样品中的平均生物标志物分布是诊断的，以及单细胞格式以区分复杂样品中的罕见（例如患病）细胞（例如， 血液）。
