Protein Assays 
Protein quantitation is often necessary before processing protein samples for isolation, separation and analysis by chromatographic, electrophoretic and immunochemical methods. Total protein estimation.

Protein Assay Selection Guide 
Brief overview of available protein assay products and a selection table for side-by-side comparison of features. 


660 nm Protein Assay 
A highly reproducible and rapid protein assay that is more linear than the Bradford method and provides better compatibility with interfering substance than RC DC Protein Assays. 


BCA Protein Assay 
Pierce BCA (bicinchoninic acid) Protein Assays, the gold standard for accurately measuring protein concentration. 


BCA Protein Assay - Reducing Agent Compatible 
A specialized form of the BCA Protein Assay that is compatible with reducing agents at concentrations routinely used in protein sample buffers. 


BSA and BGG Protein Assay Standard Sets 
Purified and calibrated concentrations of bovine serum albumin (BSA) and bovine gamma globulin (BGG) for use as standards in protein assays. 


Compat-Able Protein Assay Kits 
Reagent kits for eliminating interfering substances from protein assay samples by selectively precipitating the protein so that non-protein components to be removed easily. 


Coomassie (Bradford) Protein Assay  
A Bradford protein assay kit that is with a ready- to-use dye-binding reagent formulation for fast (almost immediate) color development. 


Coomassie Plus (Bradford) Protein Assay 
As fast as the original coomassie assay, with increased accuracy. A high-performance Bradford reagent. 


Glycoprotein Carbohydrate Estimation Kit 
A complete kit for determining the approximate mass contributed by oxidizable sugars in purified glycoproteins.  


Micro BCA Protein Assay 
All the benefits of the original Pierce BCA Protein Assay but optimized for dilute protein solutions from 0.5-20 µg/ml. 


Modified Lowry Protein Assay 
All the accuracy of the original Lowry Protein Assay, the most referenced protein assay in the world, but this protein assay has been modified so it’s ready-to-use and stable for at least one year! 


Phosphoprotein Phosphate Estimation Assay Kit 
Determine the approximate mass and molar level of serine- and threonine-phosphorylation of any purified protein.  


Protease Assay 
Ideal choice for performing routine assays necessary during the isolation of proteases, or for identifying the presence of contaminating proteases in protein samples.  


Quantitative Peroxide Assay Kits 
Simple assays for detecting the presence and amount of peroxides in both aqueous and lipid-containing laboratory reagents. This is an easy way check for contamination that may be harmful to your samples.
