What super-resolution technique is right for me?

The prospect of using super or enhanced resolution techniques and improving resolution within light microscopy is an exciting prospect, but faced with a whole host of acronyms; SIM, STED, PALM, GSDIM, RESOLOFT to name a few, the prospect of actually picking a technique is less exciting. 

Within the Wolfson Bioimaging facility we have a range of techniques to push the resolution limits of light microscopy:

Each of these techniques have different strengths and weaknesses and the choice of which one is best for your project will ultimately be led by the sample and the questions you wish to answer, the highest resolution isn’t always the best option…

The table below is designed to provide a quick overview of the techniques available within the facility and how they compare. Judgements in this table are made by how these techniques perform within the facility, with our current hardware and software options.

More details on each of the techniques can be found using the links above, and should be consulted before committing to a particular technique to ensure your project runs as efficiently as possible. As always, the facility team are always available to answer any questions or discuss projects should you need more information or require further advice.

what is the highest Z resolution possible?

Can I use samples I have already prepared for confocal?

         

Can I do more than 2 colour imaging?

   ‌      

Does it work well at depth? (>50um)

         

Is it readily compatible with dynamic live cell imaging?

         

Is it ‘optical super resolution’? (i.e. no reliance on computer reconstruction etc.)
