    • This disclosure provides compositions and methods for a low-avidity, high-affinity and high-specificity biomolecular interaction that is rapidly reversible under physiological conditions. The methods comprise linking biological targets (such as molecules, proteins, DNA, cells, etc.) with polymers and anti-polymer ligands and a way to reverse their binding using physiologically compatible polymeric compounds. The methods also comprise a way to combine different polymer/anti-polymer systems for orthogonal labeling. The compositions comprise labels including particles (fluorescent, magnetic, dense, etc.) conjugated to polymers or labels conjugated to anti-polymer antibodies. The compositions also comprise biomolecules (proteins, antibodies, DNA, etc.) conjugated to the polymers. These methods and compositions represent a major improvement to the state-of-the-art. They are particularly useful for separation and isolation of biological targets using particles, but have important application to other fields including fluorescent imaging.
    • 本公开提供了在生理条件下快速逆转的低亲合力,高亲和力和高特异性生物分子相互作用的组合物和方法。 所述方法包括将生物学靶标(例如分子,蛋白质,DNA,细胞等)与聚合物和抗聚合物配体连接,以及使用生理上相容的聚合化合物来逆转其结合的方法。 所述方法还包括将不同聚合物/抗聚合物体系结合以进行正交标记的方法。 组合物包含与聚合物或缀合至抗聚合物抗体的标记缀合的颗粒(荧光,磁性,致密性等)的标记。 组合物还包含与聚合物缀合的生物分子(蛋白质,抗体,DNA等)。 这些方法和组成代表了对最先进技术的重大改进。 它们对于使用颗粒的生物靶标的分离和分离特别有用,但在包括荧光成像在内的其他领域具有重要应用。
