WebJan 17, 2024 · Introduction. A Serial dilution is a series of dilutions, with the dilution factor staying the same for each step.The concentration factor is the initial volume divided by the final solution volume. The dilution factor is the inverse of the concentration factor. For example, if you take 1 part of a sample and add 9 parts of water (solvent), then you have … WebConventional enzyme 5 buffer system The Five Buffer System ensures the optimum reaction conditions for each restricton enzyme. Dilution buffer Some restriction enzymes require unique buffers for optimal digestion. For Research Use Only. Not for use in diagnostic procedures.
