Isulfhydryl reagents with K+ transport in adrenal chromaffin granules
Languages of publication
In the present study the functional role of SH groups in the Ca2+ -independent K+ selective channel activity in the membrane of bovine adrenal gland chromaffin granules has been studied. Ionic channel activity has been estimated using 86Rb+, a K+ analogue, flux measurements. The inhibition of chromaffin granules K+ channel by SH modifying agents, such as N ethylmaleimide, mersalyl and phenylarsenoxide, is described.
