维百奥生物代理Spherotech品牌全系列产品
Spherotech成立于1992年，专注于为生物医学和诊断应用领域生产与供应均一性微球，公司提供高品质乳胶、荧光、顺磁性、铁磁性及多色微球产品。微球表面化学结构可通过功能基团修饰以适应不同应用场景。同时生产包被抗体、蛋白或配体（如抗生物素蛋白、链霉亲和素和生物素）的微球以及用于流式细胞仪对齐、校准、补偿、计数与分选的流式级微珠。Spherotech生产的微球广泛应用于荧光免疫分析、酶联免疫分析（EIA）、荧光显微镜技术、共聚焦荧光显微镜技术、流式细胞术/图像细胞术、磁性细胞分选、磁性颗粒酶免疫分析法、微流控技术以及其他科研与工业应用等领域。
▍Spherotech产品线
● 聚苯乙烯颗粒：聚苯乙烯颗粒是通过使用乳液聚合工艺。Spherotech 提供的颗粒已使用混床离子交换或通过离心。通常不需要用户进一步清洁。颗粒的大小由 NICOMP 激光颗粒确定尺寸测量或通过扫描电子显微镜目视。
● 交联聚苯乙烯颗粒：提供范围广泛的交联聚苯乙烯颗粒。生产不均匀、形状均匀和多孔交联聚苯乙烯颗粒。当颗粒形状无关紧要时，低成本的非均匀颗粒很有用。如果需要完美的球形单一尺寸聚合物颗粒，请使用0.5% DVB 交联聚苯乙烯颗粒。还提供均匀的交联聚苯乙烯颗粒，在有机溶剂存在下保持稳定。多孔交联珠将提供额外的表面积。此外，还提供更大尺寸的均匀交联聚苯乙烯颗粒。
● 荧光颗粒：具有单个或多个荧光团的荧光颗粒有各种尺寸、发射光谱和组合。许多适用于流式细胞术、荧光显微镜、吞噬作用研究和细胞标记。SPHERO™荧光微粒的制备方法是用适当的荧光团溶液对颗粒的聚苯乙烯芯进行染色，或者在聚苯乙烯芯颗粒存在下在苯乙烯中聚合荧光团。因此，可以制备各种各样的荧光颗粒，其大小、荧光团类型、荧光强度和表面官能团各不相同。大多数用于制备 SPHERO™ 荧光颗粒的荧光团都是不溶于水的，因此非常稳定。这些荧光团一旦掺入颗粒中，就不会浸出，并且在适当的储存条件下，它们的颜色和荧光可以长时间保持稳定。
