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

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

A true isopycnic centrifugation method for the study of the bovine nasal cartilage proteoglycan polydispersity is presented. The use of cesium sulfate as gradient forming salt instead of cesium chloride allowed proteoglycan banding without any sedimentation at the bottom of

A novel compound, TTP-8307, was identified as a potent inhibitor of the replication of several rhino- and enteroviruses. TTP-8307 inhibits viral RNA synthesis in a dose-dependent manner, without affecting polyprotein synthesis and/or processing. Drug-resistant variants of coxsackievirus B3 were all
