Abstract

Ca2+ transients in cardiac myocytes measured with high and low affinity Ca2+ indicators.

Authors:Berlin JR,Konishi M

Journal:Biophysical journal

PubMed ID:8274651

Intracellular calcium ion ([Ca2+]i) transients were measured in voltage-clamped rat cardiac myocytes with fura-2 or furaptra to quantitate rapid changes in [Ca2+]i. Patch electrode solutions contained the K+ salt of fura-2 (50 microM) or furaptra (300 microM). With identical experimental conditions, peak amplitude of stimulated [Ca2+]i transients in furaptra-loaded myocytes ... More

Matrix free Mg2+ changes with metabolic state in isolated heart mitochondria.

Authors:Jung DW, Apel L, Brierley GP

Journal:Biochemistry

PubMed ID:2361136

'The concentration of free Mg2+ in the matrix of isolated heart mitochondria has been monitored by using the fluorescent probe furaptra (mag-fura-2). Beef heart mitochondria respiring in a KCl medium in the absence of external Mg2+ maintain free matrix Mg2+ near 0.50 mM. Addition of Pi under these conditions decreases ... More

Modulation of Mg2+ efflux from rat ventricular myocytes studied with the fluorescent indicator furaptra.

Authors:Tursun P, Tashiro M, Konishi M

Journal:Biophys J

PubMed ID:15626700

'The fluorescent Mg(2+) indicator furaptra (mag-fura-2) was introduced into single ventricular myocytes by incubation with its acetoxy-methyl ester form. The ratio of furaptra's fluorescence intensity at 382 and 350 nm was used to estimate the apparent cytoplasmic [Mg(2+)] ([Mg(2+)](i)). In Ca(2+)-free extracellular conditions (0.1 mM EGTA) at 25 degrees C, ... More

Mg2+ buffering in cultured chick ventricular myocytes: quantitation and modulation by Ca2+.

Authors:Koss KL, Putnam RW, Grubbs RD

Journal:Am J Physiol

PubMed ID:8498485

'To characterize the Mg2+ buffering of cultured chick ventricular myocytes, cytosolic Mg2+ was increased by liberating Mg2+ normally chelated by ATP upon total depletion of ATP content. Because the total Mg content and cell volume remained constant during this time, the difference between the amount of Mg2+ liberated (2.7 mM) ... More

Capacitative Ca2+ entry is closely linked to the filling state of internal Ca2+ stores: a study using simultaneous measurements of ICRAC and intraluminal [Ca2+].

Authors:Hofer AM, Fasolato C, Pozzan T

Journal:J Cell Biol

PubMed ID:9442108

'ICRAC (the best characterized Ca2+ current activated by store depletion) was monitored concurrently for the first time with [Ca2+] changes in internal stores. To establish the quantitative and kinetic relationship between these two parameters, we have developed a novel means to clamp [Ca2+] within stores of intact cells at any ... More
