Descrizione

Descrizione generale

CAPSO is a useful secondary standard buffer. Second dissociation constant pK₂ value of CAPSO has been measured. Useful pH range for CAPSO is 8.9 - 10.3.

Applicazioni

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.
