Seven current methods of protein quantitation, Bradford (standard, micro, and 590/450 nm ratio), Lowry, bicinchoninic acid (BCA), UV spectrophotometry at 280 nm, and Quant-iT fluorescence-based determination, were compared with regard to their suscep

The exchange sites of montmorillonite (M) were made homoionic to calcium (Ca), hexadecyltrimethylammonium (HDTMA) or pyridinium (PY) cations. The clays were used as adsorbents for the enzyme, catalase (CA). Equilibrium adsorption and binding isotherm
