Stanniocalcin (STC) is a calcium- and phosphate-regulating hormone produced by the corpuscles of Stannius in fishes. A rise in ion calcium (Ca2+) levels is the principal stimulus for secretion, and the hormone acts on the gills, gut, and kidneys to r

The corpuscles of Stannius are responsible for the synthesis and secretion of stanniocalcin (STC), a glycoprotein hormone that regulates calcium and phosphate homeostasis in fishes through its actions on the gills and kidneys. The corpuscles of Stann

A rainbow trout fry bioassay based on 45 Ca uptake was used to compare the effects of pure coho salmon teleocalcin (TC) and several synthetic peptide fragments of TC. Calcium uptake in the fry exhibited a cycle, with an amplitude variation of 3.3 to

This report describes the isolation of teleocalcin, a glycoprotein hormone from the corpuscles of Stannius (CS) of sockeye salmon (Oncorhynchus nerka), using affinity, gel exclusion, and ion exchange chromatography. In discontinuous, gradient (10-20%

This report describes the characterization of an antiserum to salmon teleocalcin, a glycoprotein hormone that has recently been isolated from sockeye salmon, Oncorhynchus nerka, corpuscles of Stannius (CS). Immunodiffusion studies showed that teleoca

The Ca 2+ -binding properties of placental plasma membranes were studied using a flow dialysis system. Ca 2+ -binding was not detectable at pH 4.0, but increased at higher pH values to a maximum binding at pH 11.0. Two types of Ca 2+ -binding sites w
