The Effect of Calcium Ionophores on Fragmented Sarcoplasmic Reticulum [PDF]

open access: yesThe Journal of General Physiology, 1972
X-537 A and A 23187, two antibiotics which form liphophilic complexes with divalent cations, function as ionophores in vesicular fragments of sarcoplasmic reticulum (SR). Addition of either ionophore to SR preloaded with calcium in the presence of adenosine triphosphate (ATP), causes rapid release of calcium. Furthermore, net calcium accumulation by SR

Ionophore-based Heterogeneous Calcium Optical Titration [PDF]

open access: yes, 2017
Recently, the field of complexometric titration significantly progressed with the advent of ionophore-based titration reagents. We present here for the first time an ionophore-based heterogeneous optical titration method for calcium.

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).

Calcium ionophore and acetylcholine dilate arterioles on the mouse brain by different mechanisms. [PDF]

open access: yes, 1989
Pial arterioles on the surface of the mouse brain were observed in vivo under a chamber with a glass window. When placed under the window, calcium ionophore, acetylcholine, and previously acidified sodium nitrite each dilated the arterioles.

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 ...
