Did you know that just 100-200 gold particles in your #immuno-EM data can give you an incredibly good idea of the #labelling distribution and reveal positive signals that you may not immediately recognise? It's amazing how reproducible this " #100-gold-method" is. #stereology doi.org/10.1369/jhc....

An electron micrograph reveals numerous bacteriophages attached to a single bacterium. These viruses, far outnumbering any other life form on Earth, are potential allies in fighting bacterial diseases. The image showcases their minuscule size and unique structure, highlighting the phage's protein coat and genome (DNA or RNA).
