CLC Chloride Channels: Structure, Function, and WebCell fluorescence was related to intracellular chloride by a Stern-Volmer relation with a quenching constant of 12 M-1. Intracellular SPQ calibration was performed using the ionophores nigericin and tributyltin, high external potassium concentrations, and varying extracellular chloride concentrations.

Several chemical factors affect the ionophore activity. The activity of an ionophore-metal complex depends on its geometric configuration and the coordinating sites and atoms which create coordination environment surrounding the metal center. This affects the selectivity and affinity towards a certain ion. Ionophores can be selective to a particular ion but may not be exclusive to it. Ionophores facilitate the transport of ions across biological membranes most commonly via pas… WebTributyltin chloride (Bu 3 SnCl or tri-n-butylstannane) is an organotin compound that can be used as a reagent for: The synthesis of fluorinated stannanes by reacting with …
Web1 jun. 2006 · The tributyltin carboxylates exhibited good sensitivity and significant chloride selectivities, while the corresponding triphenyltin benzoates were much less active. Web1 apr. 2003 · Ionophores are highly lipophilic polyethers that accumulate in cell membranes and catalyze rapid ion movement. When sensitive bacteria counteract futile ion flux with membrane ATPases and transporters, they are eventually de-energized.
WebTributyltin (TBT) is generally less toxic than trimethyl- and triethyltins. Tributyltin compounds are moderately toxic via both ingestion and dermal absorption. The tributyltin compounds may be strongly irritating to the skin in humans, especially the hair follicles, and skin exposure may result in chemical burns in only a few minutes if the Web1 aug. 2012 · Accordingly, at the end of each experiment cells were exposed to a series of calibration solutions containing the ionophores tributyltin (a Cl − /OH − exchanger; Sigma-Aldrich) and nigericin (a K + /H + exchanger; Sigma-Aldrich). Under steady-state conditions, [Cl −] o and [Cl −] i were assumed to be equal.
