Ionophore nigericin
WebIn summary care must be taken when using the putative K+/H+ ionophore nigericin as an experimental tool in synaptosomes, as under standard conditions (i.e. in the presence of high external Na+) nigericin behaves as a Na+/H+ ionophore. Publication types Research Support, Non-U.S. Gov't MeSH terms Animals WebProduct name Nigericin Na+ salt, K+ ionophore Description K + ionophore Biological description K + ionophore; exchanges K + for H + across most biological membranes. …

WebNigericin is a carboxylic ionophore that exchanges K + (and to a lesser extent Na +) for H + across cell membranes. If one is successful in choosing [K +] o to match [K +] i, then … Web21 dec. 2004 · The selectivity of nigericin for Pb(2+) exceeds that of ionomycin or monensin and arises, at least in part, from a high stability of nigericin-Pb(2+) complexes. Plots of …
WebNigericin is a carboxylic ionophore that exchanges K + (and to a lesser extent Na +) for H + across cell membranes. If one is successful in choosing [K +] o to match [K +] i, then … WebNigericin is a carboxylic ionophore that exchanges K + (and to a lesser extent Na +) for H + across cell membranes. If one is successful in choosing [K +] o to match [K +] i, then pH i should equal pH o. Thus, by altering pH o, one can measure the dye's spectral properties over a range of pH i values.
Web1 dec. 2013 · The release of IL-1beta in response to nigericin, a potassium ionophore, and maitotoxin, a potent marine toxin, was also found to be dependent on cryopyrin. In contrast to Asc-/- macrophages, cells deficient in the gene encoding cryopyrin (Cias1-/-) activated caspase-1 and secreted normal levels of IL-1beta and IL-18 when infected with Gram … WebNigericin sodium salt is a potassium ionophore, exchanges K + for H + across biological membranes, in a similar manner to Valinomycin (Cat. No. 3373). Stimulates mitochondral …
WebLike nigericin, the ionophores A204 and lasalocid induced the release and maturation of IL-1 beta. The electrogenic potassium ionophore valinomycin, however, did not stimulate these post-translational events. Addition of nigericin or lasalocid to LPS-stimulated cells produced a rapid intracellular acidification; ...
WebNigericin has been employed to study anion transport (Section 2.5) and to modify the pH gradient across energy-conserving membranes. It is often stated that nigericin abolishes ΔpH across a membrane; in fact, the ionophore equalises the K + and H + concentration gradients, with the final ion gradients depending on the experimental conditions. iphone headphones adapters ebayWeb12 okt. 2015 · Nigericin, a K +,H +-ionophore 1-21 with antibiotic 10, 22-26, antimalarial 27, anti-Toxoplasma gondii 28 and antiviral 11, 29, 30 potency, has been considered for … iphone hdr怎么开Web15 apr. 2016 · The role of carboxylic ionophores (including nigericin and monensin) in lysosomal protein degradation was shown previously, and interestingly monensin inhibited autophagy (29). Thus, monensin and nigericin produced opposite effects on pH and on autophagy and mitophagy that again, suggests the effect of intracellular pH on … iphone headphone adapter appleWebThe term ionophore (from Greek ion carrier or ion bearer) was proposed by Berton Pressman in 1967 when he and his colleagues were investigating the antibiotic mechanisms of valinomycin and nigericin. [4] Many ionophores are produced naturally by a variety of microbes, fungi and plants, and act as a defense against competing or pathogenic species. iphone headphones cutting outWebNigericin sodium salt is a potassium ionophore, exchanges K + for H + across biological membranes, in a similar manner to Valinomycin (Cat. No. 3373). Stimulates mitochondral ATPase activity and disrupts membrane potential. Also acts as an ionophore for Pb 2+ with no activity with other divalent cations. iphone headphone featuresWebWell-known ionophore-antibiotics include Valinomycin, Gramicidin, Nigericin, Monensin and Monactin, which kill cells by altering ionic gradients. Valinomycin specifically transports potassium while others transports monovalent cations such as sodium, potassium, hydrogen and ammonium ions. iphone headphones dyingWebAbstract Ionophore antibiotics are compounds produced by microorganisms (mainly spore-forming bacteria) ; they act by specifically increasing the ion permeability of the cell membrane.
