Description

Application

Brij^® L23 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. Additionally, the product has also been used for assessing whether acrolein could lead to pro-enzyme activation by using gelatin zymography.

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.

Other Notes

Non-ionic polyoxyethylene ether. Used for selective and rapid solubilization of microbial membrane aldehyde dehydrogenase.
