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
