Developing protocols and training materials for the live imaging of Drosophila via lightsheet and multiphoton microscopy

Jennifer Adcott, University of Liverpool

Lightsheet and multiphoton microscopy have been widely used to reduce photo-damage. Here these systems will be used and compared for the imaging of live Drosophila using established cancer model fly lines. A protocol will be established for sample preparation, image acquisition, through to image processing and analysis. Suitability for each technique will be compared for addressing specific questions where live imaging of small model organisms or ex vivo tissues is required. The aim will be to publish these results as a methodology paper with JoVE video protocol. 

Elucidating the artifacts and abberations of SIM and STORM super resolution imaging technologies and subsequent protocol optimisation for cells and tissue sections

Julian Mark Bowen, University of Cambridge

Once our super resolution system is installed I will attempt to identify the reasons for artifacts and aberrations within the images and develop and optimise methods to eliminate them. Sample preparation is known to be critical to obtain good images using widefield and confocal imaging but is especially important for super resolution imaging.

The Characterisation of Speciality Fibres Utilising 3-D SEM Constructed Images

Michael Brookes, University of Leeds

Distinguishing expensive speciality animal fibres such as cashmere and alpaca from cheaper fibres such as wool is an important activity. Current techniques, such as ISO 17751-2, measure fibre diameter utilising an SEM in 2 dimensions at high vacuum and susceptible to viewing errors. The study will use 3-D imaging techniques to measure and characterise speciality fibres and compare the results with that of current techniques.

The Study of Marek’s Disease Virus In Feather Follicle Epithelium

Jennifer Simpson, The Pirbright Institute

Marek's disease virus (MDV) is an alphaherpesvirus which causes a lymphoproliferative disease in chickens. Inflection occurs by inhalation of infected dander and following a complex life cycle involving infection of B and T cells, the virus is shed from the feather follicle. Vaccination is available and prevents clinical disease however it does not prevent the shedding of virus. The feather follicle is important in the transmission of MDV as the feather follicle epithelium (FFE) is the only region where fully enveloped and infectious virus particles are assembled. This study aims to identify cell tropism and describe viral morphogenesis in the FFE using immunofluorescence and transmission electron microscopy.

Comparative Analysis of Cellular Localisation of Viral Glycoproteins and Capsid Protein in Transfected Cells

Helen Todd, The Moredun Research Institute

A9.5 is a gene unique to the wildebeest-associated MCF virus, Alcelaphine herpesvirus-1. A Haemagglutinin (HA) epitope-tagged construct has been generated that can be transfected into HEK293T cells and has been found to express the A9.5 protein by Western blot. A9.5 encodes a predicted glycoprotein with a potential N-terminal signal sequence but the protein sequence has no similarity to known proteins. In order to define the cellular localization of A9.5 we will compare it with the known cell-surface viral antigen glycoprotein B (gB) and the major virus capsid protein (ORF25), by transfection of HEK293T cells and analysis by fluorescence microscopy.

Characterisation of the Migratory Properties of Additives used in Acrylic Coating on Polymer Film

Craig Holliday, Innovia Films

Polypropylene film is often coated with acrylic nano-particle formulations which contain migratory additives designed to modify the surface properties of the material.  Whilst it is possible to quantify the levels using infra-red spectroscopy, this only provides a bulk assay. 

It is hoped that a method to image the dried acrylic coating and map additive distributions on the dried surface can be developed to allow a study of the interaction of bulk levels and drying temperature on the migratory behaviour. This can then be correlated to physical and optical characteristics to optimise manufacturing conditions.
