多环芳烃半抗原在聚苯乙烯微球表面的固载及其评价
DOI: doi:10.3969/j.issn.1671-7627.2012.06.0012, PP. 58-62
Keywords: 多环芳烃,半抗原,聚苯乙烯微球,固载
Abstract:
建立分别在胺基聚苯乙烯微球和氯乙酰化聚苯乙烯微球上固定不同多环芳烃半抗原的方法。用扫描电子显微镜(sem)和傅里叶红外光谱仪(ft-ir)表征固载半抗原微球的外观形貌和表面官能团,采用紫外分光光度法测定固定化半抗原微球静态吸附多环芳烃萘和蒽的能力。结果表明:半抗原在微球表面固载成功,固定化半抗原微球单分散性好,球形度高,性质稳定;固定化半抗原微球具有良好的选择性吸附多环芳烃的能力,可以作为生物活性材料,用于抗体固载和抗体的分离和分析。
