Application

Brij®L23 solution is a detergent used for measuring the concentration of carbon black in lung tissues. It has also been used for selective and rapid solubilization of microbial membrane aldehyde dehydrogenase.

Biochem/physiol Actions

Brij®L23 also referred to as Brij 35 or Polyoxyethylene (23) lauryl ether is a non-ionic detergent that lowers the non-specific protein adsorption and reduces electroosmotic pumping drastically. This allows the pH to be varied without adversely affecting the flow rate. It also used as a nonionic surfactant that decreases the absorbance of the blank, inhibits turbidity as well as provides linearity.
