1. Lithium Ionophores for Ion Selective Electrodes

    Lithium Ionophores for Ion Selective Electrodes
    Ionophores are a chemical species that reversibly bind ions. Lithium ionophores are a lipophilic variant of these species, which means that they may be combined with lipids and are fat-soluble. What is Lithium? Lithium is a metallic element (Li) with 2 naturally occurring forms of isotopes, namely lithium-6 and lithium-7. Lithium has become a popular battery option due to its...
  2. Ion-Selective Electrodes (ISE): An Introduction

    Ion-Selective Electrodes (ISE): An Introduction
    Ion-Selective Electrodes (ISE): An Introduction Ion-selective electrodes have a wide variety of industrial and research uses. They offer a comprehensive method in testing the level of activity of ions contained within aqueous solutions. This is a necessary process to determine the electrical potential (conductivity) of a substance or solution, through potentiometry. What Are Ion-selective Electrodes? Ion-selective electrodes are also known...

  4. Ionophores: Ion Carriers and Channels for Membrane Transport

    Ionophores: Ion Carriers and Channels for Membrane Transport
    Ionophores are molecules that facilitate ion passage in or out of cell membranes. Ion carrier: A substance that can transfer ions from a hydrophilic medium, such as water, into a hydrophobic medium, i.e a biological membrane, where the ions typically would not be soluble.
  5. Valinomycin Ionophore: Frequently Asked Questions

    Valinomycin Ionophore: Frequently Asked Questions
    Valinomycin is a potent antibiotic which acts as a potassium (K+) ionophore. Induces K+ conductivity in cell membranes. Also active in vitro against Mycobacterium Tuberculosis, and as an apoptosis inducer. Valinomycin is obtained from the cells of several Streptomyces strains, among which "S. tsusimaensis" and S. fulvissimus.

  7. Nonactin based biosensors to measure ammonia

    Nonactin based biosensors to measure ammonia
    Ammonia (NH3) is a poisonous and pungent-smelling colorless gas that makes the eyes water. Ammonia is readily soluble in water. The aqueous solution has an alkaline reaction and is known as ammonia water or tincture of ammonia. In conjunction with acid, ammonia forms salts that disassociate in water, to form ammonium ions (NH4 +) and the corresponding anions. In nature...
  8. A23187: Uncouples Oxidative Phosphorylation and Inhibits ATPase

    A23187: Uncouples Oxidative Phosphorylation and Inhibits ATPase Chemical structure of calcium ionophore A23187 A23187 is a carboxylic acid antibiotic which simultaneously uncouples oxidative phosphorylation and inhibits ATPase of rat liver mitochondria incubated in a magnesium-free medium. The antibiotic acts as a freely mobile carrier to transport calcium and magnesium, but not potassium, from an aqueous medium buffered at pH 7.4...
