We previously observed that gangliosides GM2, GM1, and GM3 inhibit Ca2+-uptake via the sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) in neurons and in brain microsomes. We now systematically examine the effect of various gangliosides and their analogs on Ca2+-uptake via SERCA and

Antipyrylazo III was introduced into frog cut twitch fibers (17-19 degrees C) by diffusion. After action potential stimulation, the change in indicator absorbance could be resolved into two components that had different time courses and wavelength dependences. The first component

1. Intramembrane charge movements and changes in intracellular Ca2+ concentration were studied in voltage clamp experiments on cut twitch muscle fibres of the frog. The restoration from inactivation caused by steady depolarization and its modification by the phenylalkylamine Ca2+ channel

Fura-2 is one of the most frequently used fluorescent Ca indicator dyes; yet it has limitations in tracking large intracellular Ca transients due to its high affinity for Ca. Since high affinity is of advantage when small Ca changes are

The metallochromic indicator antipyrylazo III can be used for the rapid and convenient monitoring of Mn2+ transport in biological systems. The apparent KD of the Mn-antipyrylazo III complex in buffered 150 mM KCl (pH 7.2 at 20 degrees C) is
