The efficient immobilization of antibodies on monolithic support is one of the most critical steps when preparing immunoaffinity supports. In this work, the ADECA (amino density estimation by colorimetric assay) method was adapted to tridimensional supports (in a dynamic mode)

Protein quantification is an important step for handling protein samples for isolation and characterization; it is a prerequisite step before submitting proteins for chromatographic, electrophoretic, or immunochemical analysis and separation. Colorimetric methods are fast, simple, and not laborious. This unit

Efficient extraction and accurate quantification of nucleolar macromolecules are critical for in vitro analysis, especially for studying RNA, DNA, and protein dynamics under identical conditions. There is presently no single method that efficiently and simultaneously isolates these three macromolecular constituents

During each step of a protein isolation technique, if enzyme activity is to be determined and before a protein mixture is separated on a polyacrylamide electrophoresis gel, it is important to determine the concentration of the protein(s) in solution. Measuring

We report here substantial interference from N-hydroxysuccinimide (NHS) in the bicinchoninic acid (BCA) protein assay. NHS is one of the most commonly used crosslinking agents in bioanalytical sciences, which can lead to serious potential errors in the BCA protein assay
