MEASUREMENT METHODS - ANNOTATIONS

The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database. For more information about these vocabularies please see Shimoyama et al. Three ontologies to define phenotype measurement data. Front Genet. 2012;3:87.

Definition:A method which quantifies the net effect of blocking both Na-K-Cl cotransporters and the Na/K pump, membrane transport proteins/enzymes which transport sodium (Na), potassium (K), and chloride (Cl) ions across cell membranes. The Na+ passive permeability assay essentially measures Na+ and/or K+ leak into cells.
Synonyms:exact_synonym: bumetanide-ouabain resistant cation leak assay;   bumetanide-ouabain resistant pathway assay;   passive membrane permeability assay
