The only constant with microscopy imaging is variability in both color and image quality. You only need to look at images in journal articles, posters, around your laboratory, or compare your images with a colleague’s—the evidence is staggering. Interestingly, variability doesn’t generally come from the digital camera, rather it comes from our use of imaging…
After countless immunos with free-floating sections – troubleshooting, testing antibodies, and finally doing the actual experiments – I felt like an expert on immunohistochemistry. I knew everything there is to know, right? Well, of course not – it does not work like this in science! For my next project, I would need to perform immunohistochemistry…
When you fix your tissue samples with paraformaldehyde (PFA) the proteins in your sample become covalently cross-linked. This is good to preserve the ‘architecture’ of your tissue sample. However, this cross-linking can become a problem when you carry out immunohistochemistry (IHC). Cross-linking can ‘mask’ or hide your antigens-of-interest and make them ‘invisible’ to your IHC…
Discover the history of simple and compound microscopes in this first of our two-part series on the history of microscopes.
It doesn’t matter how excited you are about the research or how intriguing the biology is, if you cannot record it – and record it well – it won’t matter. Here I will tell you how to take the perfect electron micrograph.
It’s unclear exactly how the term ‘Special Stains’ first arose in the world of histology, but it refers to empirical and histochemical staining techniques that significantly contributed to the advancement of histology in the late 19th century. In a nutshell, these stains are ‘Special’ because they are not routine – simple as that. Therefore, Special…
