Study on calcium transport by sarcoplasmic reticulum vesicles using fluorescence probes. 1978

T Ueno, and T Sekine

Fluorescence changes of 1-anilino-8-naphthalenesulfonic acid and 3,3'-dipropyl-2,2'-thiadicarbocyanine during Ca transport by sarcoplasmic reticulum vesicles were studied. The fluorescence of both probes is enhanced corresponding to the rapid initial Ca uptake. The enhancement could be interpreted in terms of increased binding of the former (anionic) dye and decreased binding of the latter (cationic) dye to the vesicles, suggesting a change in the surface charge of the membranes associated with Ca transport. Under limited conditions where Na, K, and Mg were not added exogenously, Ca could be transported without concomitant counter-transport of these cations.

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
