摘要:

选取3 种不同聚苯乙烯-二乙烯苯基材,通过硝基化、氨基化、活化、偶联抗体等步骤制备免疫亲和柱,用于4 种镰刀菌毒素(玉米赤霉烯酮、脱氧雪腐镰刀菌烯醇、T-2毒素、HT-2毒素)的同时纯化,并将3 种基材制备的免疫亲和柱进行比较。以Cleanert PS型聚苯乙烯-二乙烯苯为基材制备的免疫亲和柱与抗体偶联的偶联率为97.64%,且其空白柱对样品的吸附作用最小,3 个加标水平下的回收率为66.16%~112.80%,相对标准偏差为3.09%~12.25%,可应用于实际样品的纯化。

Abstract:

Three kinds of polystyrene-divinylbenzene (PS-DVB) resins were selected to prepare immunoaffinity columns
(IAC) through nitration, amination, activation, and antibody coupling for the simultaneous purification of four Fusarium
toxins, zearalenone, deoxynivalenol, T-2 and HT-2 toxins. Among these, the coupling ratio of Cleanert PS-type PS-DVB
IAC was 97.64% and the absorption of its blank column for samples was the lowest. The recovery of this IAC column at
three spiked concentration levels was in the range of 66.16%–112.80%, and the relative standard deviation was between
3.09% and 12.25%. It can be applied to purify actual samples.

Key words: polystyrene-divinylbenzene (PS-DVB), immunoaffinity columns (IAC), Fusarium toxinsn
