Proteins may interfere with some assays, affecting accuracy and sensitivity. When ultrafiltration cannot be done, other chemical removal alternatives can be considered.
The BQCkit PCA deproteinizing kit ensures a protein removal efficiency over 99.3 % with very low sample dilution that includes a neutralizing solution to adjust the pH.
For the deproteinization of samples prior to assaying small molecules, glycogen, ATP, cAMP, glutathione and antioxidants. Not compatible with organic solvents, which will leave salt precipitates.
