Quoting more: > "I got the idea of using espresso as a staining agent from the circular dried stains in used coffee cups," says Claudia Mayrhofer, who is responsible for ultramicrotomy at the institute. During preparation, she cuts tissue samples into wafer-thin slices and fixes them onto sample holders. Staining is the last step before examination under the electron microscope. I'm curious about the grad student who is the second author on the research paper. Is he the one tasked with the current-SOP staining with (radioactive and poisonous) uranyl acetate? Was it his overworked-and-drowsy "oopsie" which lead to the discovery? | ||
