A routine task in the lab is to investigate the presence of your favorite protein in a range of histological samples. No doubt, staining your tissue sections using good old immunohistochemistry (IHC) would be your first choice. You just got to love a technique that has celebrated its 70th birthday, and is still used in…
What do you use if antibodies are too large for super resolution microscopy? Aptamers. These are small affinity reagents (~ 2 nm!) that interact with their target in the same way as an antibody, but without the hefty backbone attached.
While most of us have heard of super resolution microscopy, many of you may not have heard of MSIM, or Multifocal Structured Illumination Microscopy. This under-the-radar imaging technique is relatively quick, cheap (by comparison) and will allow you to get a lot of data, fast. So What is MSIM Anyway? MSIM, as I mentioned earlier,…
Microscopy is one of the fun parts of working with yeast. If you fix your cells, you can get a snapshot of the structures. Live cells microscopy using fluorescent proteins tagged proteins is even better, as you can see the dynamics and cell machinery working before your own eyes. Light Microscopy to Check for Contamination…
There are about as many protocols to prepare coverslips as there are ways to make tuna casserole. You can spend from 5 seconds to 2 days, depending on what your lab prefers. But in the end, what’s really needed? I’ve tried many protocols over the years and I’ve questioned some steps. Here I share my…
If you have ever imaged biological samples, you have likely encountered autofluorescence. That pesky background coloration you see under the microscope, which can make it difficult to distinguish your actual signal from the noise.1 When you are trying to look for something as delicate as RNA, you don’t want to be hunting for your signal…
