Description

Application

Bicinchoninic Acid Kit has been used for the protein estimation in salivary proteome samples, human embryonic kidney 293 cells and luteal cells.

Features and Benefits

• Simple, sensitive colorimetric assay for proteins
• Two stable reagents are used for the working solution
• Faster and easier than the Lowry protein assay
• Compatible with many detergents both ionic and nonionic
• Less variation between different proteins than the Bradford dye-binding assay
• Adaptable for use in microwell plates

Principle

Proteins reduce alkaline Cu(II) to Cu(I) in a concentration-dependent manner. Bicinchoninic acid is a highly specific chromogenic reagent for Cu(I), forming a purple complex with an absorbance maximum at 562 nm. The absorbance is directly proportional to protein concentration. This is an alternative to the Folin-Ciocalteu reagent for protein determination.
