一般說明

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。

應用

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）。

Balloon-occluded retrograde transvenous obliteration has been traditionally based on liquid sclerotherapy. However, overdose and systemic spillage of liquid sclerosant can cause severe complications, such as hemolysis, which lead to hemoglobinuria, allergy, acute respiratory distress syndrome, and other disorders.
