9. An introduction to Serial Block-Face (SBF) Scanning Electron Microscopy (SEM)
Presenter: Mr Jurgen Kriel
Live
Serial Block-Face (SBF) Scanning Electron Microscopy (SEM) is a powerful imaging modality that allows for 3D acquisition SEM samples at high resolution. This is of great value for biological research, as cells and tissues can be studied in their native 3D morphology which allows for a deeper understanding of cellular phenotypes associated with certain pathologies. When combined with other fluorescent microscopy techniques, SBF-SEM provides immense value for the localization and distribution of proteins, bacteria or viruses within tissues which can provide novel insights into certain disease states. This workshop will serve as an introduction to SBF-SEM and explain the workflow involved in sample preparation and image acquisition. Due to the large amount of data generated by this approach, an overview of data handling and image processing will also be given to introduce researchers to basic principles of machine learning in the era of 'Big Data'.
___
10. AMNIS ImageStreamX: Imaging Flow Cytometry
Presenter: Dr Ziv Porat
CAF will collaborate with the International Society for the Advancement of Cytometry (ISAC) to present webinars on the principles of imaging flow cytometry, including the instrument and acquisition. We also plan an online demonstration of the analysis and will attempt an online hands-on session where participants will receive files and attempt to analyse the files by themselves.
___
11. Multicolour and Spectral flow cytometry
Presenters: Dr Maria Jaimes & Dr Rui Gardner
Multi-colour flow cytometry is an invaluable tool for medical research, especially since up to 50 parameters can now be analysed simultaneously with instruments like the spectral analyser Stellenbosch University will purchase this year. However, it is essential that flow cytometrists understand the fundamental principles of panel design and setup of such experiments, so CAF will team up again with the International Society for the Advancement of Cytometry (ISAC) to conduct webinars on these important topics. A special emphasis of these webinars will be the use of spectral flow cytometry in comparison to conventional flow cytometry.
___
12. BD FACSMelody: Cell sorting
Presenter: Mrs Lize Engelbrecht
Flow Cytometry is not only useful to analyze multiple parameters in single-cell suspensions but if a certain population or populations of cells needs to be collected from a heterogeneous sample, flow cytometry combined with cell sorting can be very useful. In this webinar, we will discuss the principles of cell sorting and demonstrate how to run and sort samples on the BD FACSMelody housed in the CAF Fluorescence Microscopy Unit.

Biological sample preparation is essential in scanning electron microscopy (SEM). Flawed sample preparations can undermine the quality of results and lead to false conclusions. Thus, the aim of this talk is to equip researchers and students with the essential knowledge required to prepare samples for SEM investigations in life sciences. To obtain acceptable SEM images with good ultrastructural preservation requires careful application of the SEM sample preparation method.
