Influence of Ionophore Supplementation on Growth Performance, Dietary Energetics and Carcass Characteristics in Finishing Cattle during Period of Heat Stress. [PDF]

open access: yes, 2013
Forty-eight crossbred heifers (378.1±18 kg) were used in a 56-d feeding trial (four pens per treatment in a randomised complete block design) to evaluate the influence of ionophore supplementation on growth performance, dietary energetics and carcass ...

Effects of protein kinase C on parthenogenetic activation of pig oocytes using calcium ionophore or nitric oxide-donor

open access: yesCzech Journal of Animal Science, 2007
Porcine oocytes matured in vitro were activated for parthenogenetic development using either calcium ionophore (50μM for 10 min) or nitric oxide donor SNAP (2mM for 23.5 hours).

Matrix-free calcium in isolated chromaffin vesicles [PDF]

open access: yes, 1985
Isolated secretory vesicles from bovine adrenal medulla contain 80 nmol of Ca2+ and 25 nmol of Mg2+ per milligram of protein. As determined with a Ca2+-selective electrode, a further accumulation of about 160 nmol of Ca2+/mg of protein can be attained ...

Transport Properties of the Calcium Ionophore ETH-129 [PDF]

open access: yesBiophysical Journal, 2001
The transport mechanism and specificities of ionophore ETH-29 have been investigated in a highly defined phospholipid vesicle system, with the goal of facilitating the application of this compound to biological problems. ETH-129 transports Ca(2+) via an electrogenic mechanism, in contrast to A23187 and ionomycin, which function in a charge neutral ...
