Describe your hands-on experience with protein biochemistry methods (e.g., protein purification, gel or capillary electrophoresis, Western blotting, enzyme or activity assays). For each technique, indicate your level of independence (e.g., observation, assisted, or performed independently) and the context in which you applied it. Include any experience you have with preparing and handling complex biological materials (e.g., mammalian cells, plasma, tissues/organs).✱
