    • In accordance with the present invention, it has been discovered that introduction of hydrophilic sulfoalkyl substituents and/or hydrophilic linkers derived from homocysteic acid, cysteic acid, glycine peptides, tetraethylene oxide, and the like, offset the hydrophobicity of the acridinium ring system to produce a more soluble label which can be attached to an antibody at higher loading before precipitation and aggregation problems are encountered. Additional compounds described herein contain linkers derived from short peptides and tetraethylene oxide which increase aqueous solubility due to hydrogen bonding with water molecules. The present invention also embraces reagents for multiple acridinium labeling for signal amplification composed of a peptide bearing several acridinium esters with sulfonate groups at regularly spaced intervals for increased solubility. The invention also embraces assays employing the above-described compounds.
    • 根据本发明,已经发现,衍生自同型半胱磺酸,半胱氨酸,甘氨酸肽,四环氧乙烷等的亲水性磺基烷基取代基和/或亲水接头的引入抵消了吖啶环体系的疏水性以产生 在遇到沉淀和聚集问题之前可以以更高的负载连接到抗体上的更可溶性标记。 本文所述的其它化合物含有源自短肽和四氧化二环的连接体,其由于与水分子的氢键而增加水溶性。 本发明还包括用于多个吖啶标记用于信号放大的试剂,其由具有几个具有磺酸盐基团的吖啶酯的肽以规则间隔的间隔组成,以增加溶解度。 本发明还包括使用上述化合物的测定。
