Hazard Class IRRITANT
CAPSO (CAS: 73463-39-5) is a useful secondary standard buffer. Useful pH range for CAPSO is 8.9~10.3. CAPSO is a biological and zwitterionic buffer commonly categorized as a Good's buffers. CAPSO has many applications some of which include immunoblotting and westerns. CAPSO is used in the electrotransfer of proteins to PVDF or nitrocellulose membranes. CAPSO buffer has very low metal-binding constants and are, therefore, particularly suited to investigate metal-dependent enzymes. CAPSO a very water soluble buffering reagent, minimal reactivity with enzymes or proteins with minimal salt effects. CAPSO was used as biological buffer in the following studies: Chemiluminescent in situ hybridization using soybean peroxidase-labeled peptide nucleic acid (PNA) probes. 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.
