The conventional methods of trace metals determination in sediments or soils involves acid digestion step, but to bring those samples to the solution is time consuming and includes the use of concentrated acids such as hydrochloric acid, nitric acid, fluoric acid. Slurry sampling graphite furnace ...
Powdered dried samples (0.1 g) were subjected to 12 h digestion with a 1:5 acid mixture (80% perchloric acid + concentrated H2SO4). Then, distilled water was added to the digested samples until they reached 100 mL each. The diluted samples were then used to evaluate Cd2+ contents. The...
Unlike BoNT/E, which distributes evenly within the cytosol by diffusion, BoNT/A protease is concentrated at the inner side of the plasma membrane. It appears that double-leucine motif is the determinant of such BoNT/A localization. The binding of BoNT/A near the synaptic membrane involves ...
