说明

Brij® L4 是一种非离子表面活性剂。 它包含一个与氧乙烯头基相连的烷基 (C12) 尾。
Brij® L4 具有两亲性。 Brij L4 包含疏水和亲水区域,可以形成胶束并将疏水药物分散到胶束的核心。 这反过来又提高了药物溶解度。 Brij L4 还对乳腺癌耐药蛋白 (BCRP) 介导的药物外排产生强烈的抑制作用。 与其他常用表面活性剂相比,它能更好地抑制 Taq 吸附。 Brij L4 支持标准 Taq 浓度的皮升反应体积中的液滴聚合酶链式反应 (PCR)。

一般描述

Brij® L4 is a non-ionic surfactant. It comprises an alkyl (C12) tail attached to an oxyethylene headgroup.
 

应用

Brij® L4 has been used:
  • as a surfactant for the synthesis of copper(I) oxide (Cu2O) spherical nanoparticles using a microemulsion technique
  • as a non-ionic surfactant for preparing reverse micelles to synthesize Pt3Co alloy nanoparticles
  • as a surfactant to enhance the efficiency of interfacial coupling of hydrophobic materials and to make hydrogel

生化/生理作用

Brij® L4 exhibits amphiphilic properties. Brij L4 contains hydrophobic and hydrophilic regions that can form micelles and disperse hydrophobic drugs into the core of micelles. This in turn enhances drug solubility. Brij L4 also elicits a strong inhibitory effect against breast cancer resistance protein (BCRP) mediated drug efflux. It inhibits Taq adsorption better when compared to other commonly used surfactants. Brij L4 supports droplet polymerase chain reaction (PCR) in picoliter reaction volumes at standard Taq concentrations.
