Super-resolution Imaging of Live BY2 Cells Using 3D-structured Illumination Microscopy

Research output: Contribution to journalArticlepeer-review


Light microscopy is the standard tool for studying sub-cellular however, owing to the diffractive properties of light, resolution is limited to 200 nm. Super-resolution microscopy methods circumvent this limit, offering greater resolution, particularly when studying fluorescently labeled sub-cellular structures. Super-resolution methods such as 3D-SIM (Structured Illumination Microscopy) fill a useful niche between confocal and electron microscopy. We have previously had success using fixed plant tissue samples with £D-SIM (Bell and Oparka, 2014). However, sensitive structures can be altered by fixation and embedding procedures, so we developed a method for imaging live cells. In this protocol we used 3D-SIM to image the ER and Hechtian Strands in live, plasmolysed BY2 cells.
