Equilibrium and kinetic measurements were carried out on the denaturation of bovine liver glutamate dehydrogenase (L-glutamate:NAD(P)+ oxidoreductase (deaminating), EC 1.4.1.3) induced by guanidine hydrochloride (Gdn-HCl) in 0.2 M phosphate buffer (pH 7.3) using two types of detection, light-scattering and circular

The apolipoproteins of insect lipophorin were dissociated in guanidinium chloride and isolated by gel permeation chromatography. Over 98% of the total lipid in lipophorin was associated with apolipophorin I (apoLp-I), thus suggesting this apolipoprotein to be the lipid binding component
