WebWe showed previously that NKA (Na+/K+-ATPase) interacts with acetylated tubulin resulting in inhibition of its catalytic activity. In the present work we determined that membrane-acetylated tubulin, in the presence of detergent, behaves as an entity of discrete molecular mass (320-400 kDa) during molecular exclusion chromatography. WebMembrane potential (also transmembrane potential or membrane voltage) ... On the other hand, the sodium equilibrium potential, E Na, is approximately +66 mV with approximately 12 mM sodium inside and …
WebIn recent years, the study of dermal preparations has received increased attention. There are more and more modern approaches to evaluate transdermal formulations, which are crucial in proving the efficacy of a formulation. The aim of this study was to compare permeation across innovative synthetic membranes (Strat-M and Skin PAMPA …
