Bicinchoninic acid; BCA


Cat. No.: 10218 Category:


General Description

Bicinchoninic acid (BCA) is commonly used for the determination of protein concentration as well as a photometric reagent for protein assay. It acts by developing an intense purple complex with the cuprous ion under alkaline conditions, and hence provides a platform for the analytical monitoring of cuprous ion produced in the biuret reaction. BCA displays increased tolerance against interference from non-ionic detergents and simple buffer salts.



  • Monitor the levels of reducing sugars, thereby helping in the detection of chitinases
  • Used for determining protein concentration
