Proteinase protection assay
Webb12 okt. 2024 · We inserted a tobacco etch virus (TEV) protease cleavage site between α-synuclein and green fluorescent protein. As the TEV protease is highly specific, non-toxic, and active under physiological conditions, we are able to use protection from TEV cleavage to distinguish internalized PFFs from those which remain attached to the cell surface. WebbRNase Detection Assay Measuring Contamination by Probe Degradation. 50,000 cpm of a moderate specific activity 32P-labeled RNA were incubated with dilutions of RNase A at 37°C for 18 hrs. Probe radiolysis was assessed after separation on a 5% acrylamide/ 8 M Urea gel and autoradiography.

WebbLiterature # 9PIV302. Proteinase K, produced by the fungus Tritirachium album Limber, is a serine protease that exhibits a very broad cleavage specificity. It cleaves peptide bonds adjacent to the carboxylic group of aliphatic and aromatic amino acids and is useful for general digestion of protein in biological samples. It has been purified of ...
