We investigated the inhibitory effect of stinging nettle leaf extract on the protease activity of botulinum neurotoxin type A and B light chains. The nettle leaf infusion was fractionated and HPLC-based enzymatic assays were performed to determine the capacity of each fraction to inhibit the
Two different forms of acid invertase (EC 3.2.1.26) were extracted from expanding leaves of the stinging nettle (Urtica dioica L.). One form was soluble and could be localized within the cytosol, whereas the other was ionically bound to the cell-wall and could not be detected in protoplasts. Both
The present study investigated the effects of dietary supplementation of stinging nettle (Urtica dioica) on growth performance, skin mucus, immune response and disease resistance of rainbow trout (Oncorhynchus mykiss) fed with diets supplemented with U. dioica at 0, 1, 2 and 3%. After 8 weeks of
Experiments were performed to define the best isolation method for isolating Chrysaora fishing tentacle nematocyst organelles in order to minimize non-nematocyst contaminating proteins and proteases and stabilize crude nematocyst venom lethal activity. Techniques employed to disrupt the tentacles
