| Application: | CAPSO was used as biological buffer in the following studies: • To maintain pH 9 during water leach test for the analysis of high-carbon coal fly ash-soil mixtures. • Chemiluminescent in situ hybridization using soybean peroxidase-labeled peptide nucleic acid (PNA) probes. I • Preparation of planar bilayer lipid membranes. It may be employed as buffer for the electrophoretic analyses in non-denaturing gels, to investigate macromolecular self-association of ADP-ribosyltransferase protein in solution. |
