【摘要】 采用循环伏安法研究了1-O-烯丙基-4-羟基蒽醌(OAHAQ)的电化学行为.研究表明,OAHAQ与BSA能形成了1:1的配合物,同时研究了OAHAQ及其与BSA配合物的表观扩散系数,在BSA存在下,OAHAQ的标准速率常数Ks没有显著的变化,其还原峰电流随着BSA的加入而减小,据此可用来测定BSA的浓度.更多还原

【Abstract】 The electrochemical behavior of 1-O-allyl-4-hydroxyanthraquinone(OAHAQ) in an aqueous medium was investigated.OAHAQ can form adducts with albumin(BSA).The apparent diffusion coefficients of OAHAQ and OAHAQ-BSA adduct and the stoichiometry of OAHAQ and BSA in OAHAQ-BSA adduct were measured.In the presence of BSA,the standard rate constant Ks of OAHAQ was not significantly changed.The reduction peak current of OAHAQ decreased with the addition of BSA in the solution.The proposed method can be operated to probe the interaction between these species and to determine BSA.更多还原
