表面活性剂-Surfactants

Surfactants are commonly utilized with microspheres composed of hydrophobic polymer matrices such as polystyrene to facilitate bead wetting and to deter or treat aggregation. Common concentrations are ~0.1% for uncoated polymer beads and ≤0.05% in the storage buffer of coated polymer, magnetic, and silica beads.

Triton™ X-100 and Tween^® 20 are nonionic surfactants used in the storage buffers of coated bead suspensions, while Sodium Dodecyl Sulfate (SDS) is an anionic surfactant that decreases hydrophobicity and participates in charge stabilization of the suspension.

表面活性剂通常与由疏水聚合物基质（如聚苯乙烯）组成的微球一起使用，以促进珠润湿并阻止或处理聚集。未包被的聚合物珠子的常见浓度为 ~0.1%，而在包被的聚合物、磁性和二氧化硅珠子的储存缓冲液中，浓度为 ≤0.05%。

Triton™ X-100 和 Tween ^® 20 是非离子表面活性剂，用于包衣微珠悬浮液的储存缓冲液，而十二烷基硫酸钠 (SDS) 是一种阴离子表面活性剂，可降低疏水性并参与悬浮液的电荷稳定化。
