一般描述
Brij® L4 是一种非离子表面活性剂。它含有一个连接氧乙烯基头基的烷基（C12）尾。
应用
Brij® L4 已被用于：
- 作为表面活性剂采用微乳液技术合成氧化铜（I）（Cu2O） 球形纳米颗粒
- 作为非离子表面活性剂用于制备反胶束以合成Pt3Co 合金纳米颗粒
- 作为表面活性剂用于改善疏水材料界面偶联的效率并生成水凝胶
生化/生理作用
Brij® L4 具有两亲性。Brij L4 含有疏水和亲水区域，可以形成胶束并使疏水药物分散进入胶束核中。这相应地改善了药物的溶解性。Brij L4也对乳腺癌耐药蛋白（BCRP）介导的药物外排有强烈的抑制作用。与其它常用表面活性剂相比，它对Taq吸附的抑制作用更强。Brij L4 有助于在标准Taq浓度下进行皮升反应体积的液滴聚合酶链式反应（PCR）。
