摘要:

制备环丙沙星(Cip)抗生素的免疫亲和柱(IAC),研究优化IAC 柱的鉴定和洗脱条件,并测试其最佳性能,最终洗脱液选择4ml 50% 的甲醇,在重复使用5 次后,其柱容量仍能达到开始柱容量的25% 左右,采用高效液相色谱荧光检测器(HPLC-FLD)对IAC 进行回收率测定,以0.05% 的甲酸水溶液- 甲醇体系作为流动相,梯度洗脱HPLC-FLD 方法的线性范围10~1000ng/ml,相关系数大于0.99,测定出IAC 柱对环丙沙星的回收率为74.38%~105.552%。

Abstract:

In order to prepare optimal immunoaffinity column (IAC) for ciprofloxacin, elution parameters and separation efficiency were systematically analyzed. The excellent separation performance was observed using 4 ml of 50% methanol in PBS as elutent. Column capacity remained 25% of original capacity after 5 cycles of use at the optimized condition. Recovery rate determination was conducted using high performance liquid chromatography with a fluorescence detector (HPLC-FLD) under the gradient elution through 0.05% formic acid aqueous solution-methanol. The HPLC-FLD method exhibited an excellent linear in the range of 10-1000 ng/ml with a correlation coefficient of 0.99. Recovery rate of ciprofloxacin using IAC was 74.38%- 105.552%.

Key words: quinolones, ciprofloxacin, immunoaffinity column (IAC)
