In this study, we compared in vitro calcium binding by the taurine and glycine conjugates of the major bile acids in human bile: cholic (CA), chenodeoxycholic (CDCA) and deoxycholic (DCA) acids, together with the cholelitholytic bile acids ursodeoxycholic (UDCA) and...

The influence of two commonly used sulphonate buffers, PIPES and MES, on the in vitro assembly of bovine brain microtubule protein was examined. Microtubule assembly was monitored by turbimetry and, after centrifugation, the polymerised protein was analysed by SDS-PAGE and...

Different types of unusual dynamic behavior have been reported for steady-state microtubules. While almost all earlier reports relied on kinetic measurements of bulk polymerization, we have directly visualized the steady-state addition of subunits to individual microtubules through the use of...

An impurity, probably an anion, present in some batches of the buffer substances 4-(2-hydroxyethyl) piperazine-1-ethanesulfonic acid (HEPES), 2-morpholinoethane sulfonic acid (Mes) and piperazine-1,4-bis(2-ethane sulfonic acid (Pipes), activates the soluble 5'-nucleotidase from rat kidney. The affinity of the enzyme for 5'-IMP...

Hyperosmotic solutions inhibit exocytosis of catecholamine from adrenal chromaffin cells at a step after Ca2+ entry into the cells. The possibility that the inhibition resulted from an inability of shrunken secretory granules to undergo exocytosis was investigated in cells with...
