Research Assistant - Protein trafficking in mammalian cell models of Motor Neurone Disease (Fixed Term)

Fixed-term: The funds for this post are available for 1 years in the first instance.

Applications are invited for a Research Assistant role in the Centre for Misfolding Diseases to assist in studies related to the development of a real-time imaging cell model of TDP-43 towards understanding how the trafficking of this protein relates to Motor Neurone Disease (MND). The project involves producing transfected mammalian cell lines over-expressing TDP-43 and monitoring the translocation of the protein using immunohistochemistry and confocal microscopy.

The successful candidate will use transient transfection techniques (lipofection, Neon transfection system) to introduce TDP-43 and mutational variants to mammalian cell lines. Using these cell lines, the successful candidate will image the protein over time and use immunohistochemistry to perform co-localisation experiments with a variety of biological markers. Real time imaging using bisarsenical dyes will be performed to follow the real-time translocation and trafficking of the protein and biochemical analysis of cell lysates, including immunoprecipitation and western blotting techniques will be used to fully characterise the model. Other duties may include, but are not limited to, recombinant expression of TDP-43 variants in E.coli and protein purification (affinity and size-exclusion chromatography) and site-directed mutagenesis.

The successful candidate will have a B.Sc degree (or equivalent) in a relevant biological science. A fundamental background in cell biology is essential. They will be highly motivated, have excellent organisational skills and be able to work independently. The successful candidate will have experience in tissue culturing techniques, immunohistochemistry and confocal microscopy imaging. They will be familiar with DNA plasmid purification and site-directed mutagenesis. Some experience with recombinant protein expression and purification is desirable but not essential. Knowledge of real-time confocal microscopy would be an asset.
