20×wash solution:Dilute with Distilled or deionized water 1:20. Assay procedure 1. Prepare all reagents before starting assay procedure. It is recommended that all Standards and Samples be added in duplicate to the Microelisa Stripplate. 2. Add standard: Set Standard wells, testing sample wells...
In the contact ion pair, the Ca2+cation has a first coordination sphere containing 5 or 6 water molecules. The minimum free-energy path for dissociation involves a two-step process: First one or two additional water molecules enter the cation coordination shell, increasing the coordination number...
The resulting Ca2+ properties in water are shown in Table 1. As can be seen, the hydration free energy (ΔGh), the first-peak position of the radial distribution function of water around Ca2+ (R1), and the number of coordinated water molecules in the first solvent shell (NC) have all...
背景资料CA2 is a cytosolic enzyme with the highest activity among all known CAs.The carbonic anhydrases (ACs) form a family of enzymes that catalyze the rapid interconversion of carbon dioxide and water to bicarbonate and protons (or vice versa),a reversible reaction that occurs relatively slowly...
Chilling-sensitive rice varieties acquire chilling tolerance when their roots are exposed to short term water stress (0.5 M mannitol, 30 min). Pharmacological experiments using various Ca 2+ channel blockers suggested that the water stress signal gives rise to Ca 2+ flux, resulting in induction ...
Fura-FF has also been used in combination with FluoZin-3 (Fluorescent Indicators for Zn2+ and Other Metal Ions—Section 19.7) for simultaneous detection of Ca2+ and Zn2+. Both the water-soluble potassium salt and membrane-permeant AM ...
