monophosphate esters, sulfate esters, and carboxylic acids, with high specificity. Immobilization of the compound provided a reagent capable of binding and retaining nanomolar quantities of pyrophosphopeptide in the presence of cell lysate. The high affinity and specificity of the reagent makes it an attractive tool for the study of in vivo pyrophosphorylation.
据报道,一种树脂结合的双核锌(II)络合物可选择性捕获焦磷酸肽。该金属络合物具有高特异性地将二磷酸酯结合在其他阴离子基团上,例如单磷酸酯,硫酸酯和羧酸。化合物的固定化提供了一种能够在细胞裂解液存在下结合并保留纳摩尔量的焦磷酸肽的试剂。该试剂的高亲和力和特异性使其成为研究体内焦磷酸化的诱人工具。
