a3. Determine each pH value by comparing color of the mixed solution with the colorimetric analysis chart provided. (Obtainable pH value can vary according to quality of the source water, water inflow pressure and water temperature) 3. 确定每个PH值通过混杂的解答的颜色与提供的比色分析图比较。 (...
L-Histidine molecules were reported to bind to domain III clusters at both ends of each dimer, with a stoichiometry of 1:2 dimer:L-histidine to stabilize the hexameric form. Binding of L-histidine reorients some of the key residues in the active site. Download: Download high-res image (...
Determining the label to target ratio, also known as the degree of labeling (DOL), is crucial for quantitative fluorescence microscopy and a high DOL with minimal unspecific labeling is beneficial for fluorescence microscopy in general. Yet robust, versa
(Fig.5c, d). Aligning the origin of each displacement to a common location, we were able to track the movement of molecules (Fig.5e). To ensure an unambiguous separation between the condensate interior and interface, we chose a segmentation threshold that guards against finite size artifacts,...
promising because each fresh monolayer requires less than 500 microgram of the crown ether. The response time of ionophore was within a minute and the shelf life of the electrode either on use or idle, was found to be a three months period. The electrode surface can be re-coated and used...
