An introduction to the methodology of expansion microscopy.

An introduction to the methodology of expansion microscopy. Int J Biochem Cell Biol. 2020 May 11;:105764 Authors: Faulkner EL, Thomas SG, Neely RK Abstract Expansion microscopy is a novel, fluorescence imaging technique, which allows three-dimensional nanoscale imaging of specimens on a conventional fluorescence microscope. This is achieved through an innovative sample treatment, which culminates in approximately 4.5-fold expansion of specimens in each dimension. This allows 70 nm lateral and 200 nm axial resolution. To further develop application of the technique, there has been considerable focus on improving the methodology by i) extending the efficacy of labelling, ii) enabling multi-colour labelling of different biomolecules simultaneously, iii) further improving resolving power through alterations to sample preparation and iv) by combination of expansion microscopy with other well-established super resolution techniques. This review will highlight some of these recent advances and suggest ways that the technique could be developed further in the future. PMID: 32407880 [PubMed - as supplied by publisher]
