General description
微粒或乳胶珠，通常称为聚苯乙烯微粒，是带负电的胶体颗粒。微粒是通过苯乙烯在受控条件下的聚合反应产生的。反应的有利环境诱导自发形成聚结珠。 生物素-链霉亲和素系统是已知的最强的非共价生物相互作用，具有解离常数K(d)，数量级为4x10(-14) M。[1] 珠子本身是具有磁性的，并涂有链霉亲和素以增强结合。微粒或乳胶珠在由聚合物颗粒和水组成的水溶液中提供。聚苯乙烯′在589 nm 处折射率为1.5905；在486nm 处折射率为1.602。
超顺磁聚苯乙烯颗粒
Application
微粒子或乳胶珠用于多种应用，如：
- 电子显微镜术。
- 细胞计数仪校准。
- 免疫诊断学，尤其是乳胶凝集试验和
- 吞噬作用研究。
易与生物素结合，使其可用于多种检测试验。
