Ultracentrifugation is a powerful technique for separation of biological molecules and chemical products. LJMU currently possesses a floor model ultracentrifuge which is useful for preparative procedures. A benchtop ultracentrifuge would enable powerful analytical approaches for projects in biology, chemistry, and pharmaceutical science. This will also increase capacity for projects requiring ultracentrifugation procedures.

Study of: mitochondrial membrane protein complexes; inter-organelle communication; protein aggregates in muscle; macrovesicles; exosomes; nanoparticles; separation of lipoproteins.
