High impact information on NSC371716

  • The impermeant dye antipyrylazo III was used to measure depletion of extracellular calcium and net influx of calcium through the sarcolemma during the cardiac action potential [1].
  • Sarcolemmal Ca2+ movements in frog ventricular strips were measured by monitoring Ca2+ depletion from the extracellular space with an impermeant Ca indicator dye, antipyrylazo III [2].
  • We have used a spectrophotometric method to monitor mean free extracellular calcium concentrations in isolated left atria of guinea pigs via extracellular application of the calcium-sensitive absorption dyes, antipyrylazo III and tetramethylmurexide [3].
  • Null point titration techniques have been developed for measurements of cytosolic free Mg2+ in isolated cells and matrix free Mg2+ in isolated mitochondria using antipyrylazo III as a spectrophotometric Mg2+ indicator [4].
  • Detergent incorporation affected neither the calcium-dependent phosphorylation from ATP, as judged from multimixer quenching experiments, nor the calcium-releasing transition between the two phosphoenzyme forms (Ca2E1P to E2P), as judged from kinetically resolved dual-wavelength measurements with the calcium-sensitive dye antipyrylazo III [5].

Biological context of NSC371716

  • Cells were loaded with 10 pl doses of the Ca2+ buffer antipyrylazo III (ApIII) at specific times in the cell cycle to attempt a competitive inhibition of Ca2+-dependent steps in NEB and initiation of mitosis [6].
  • For antipyrylazo III, the relaxation rate is much faster, less than 1 ms, and the complexing kinetics can be covered with only a CaAp complex [7].
  • The stoichiometry of the interactions of antipyrylazo III with Ca2+, Mg2+, Ba2+, Sr2+ and Zn2+ ions and the relevant binding constants were studied by principal component analysis (PCA) of the absorption spectral changes [8].
