Description:
The BCA Protein Assay combines the well-known reduction of Cu2+ to Cu1+ by protein in an alkaline medium with the highly sensitive and selective colorimetric detection of the cuprous cation (Cu1+) by bicinchoninic acid. Two molecules of BCA chelate with one cuprous ion forming purple-coloured product. The BCA/copper complex is water-soluble and exhibits a strong absorbance at 562nm. Protein concentration can be determined based on absorbance because of the linear relation between them.

Features:
 

• Faster and easier than the Lowry method
• Sensitive, The minimum detection level of 25μg/ml.
• Compatible with most detergents(SDS/TritonX-100/ Tween20/Tween60/Tween80 up to 5%).
• Good linear range from 20-2000μg/ml.
• Coefficient of variation lower than Bradford.
