2008-1-1 · The role of renal ATP7B appears to be to fine-tune the intracellular copper concentration, likely by transporting copper into intracellular vesicles. Our data suggest that inactivation of ATP7B may cause local changes in copper concentrations that trigger trafficking of ATP7A toward plasma membrane for the restoration of copper balance.
2017-7-27 · Intracellular sodium concentration ("a+],) can be measured using SBFI with image analysis or spectrofluorometry.
