Mary Osborn (born in 1940)[4] is a L'Oréal-UNESCO Women in Science Award-winning English cell biologist who, until she stopped running an active laboratory in 2005,[5] was on the scientific staff at the Max Planck Institute for Biophysical Chemistry, Göttingen, Germany.[5] Osborn established two techniques frequently used by cell biologists. She pioneered both molecular weight determination of proteins using SDS PAGE[6] and immunofluorescence microscopy.[7] Osborn also used the immunofluorescence microscopy method to work out the details of the eukaryotic cytoskeleton. Small differences in the intermediate filament constituents helped her distinguish differentiated cells from each other.[8] She also found intermediate filament immunofluorescence differences between normal versus cancer cells.[8] Mary Osborn has been a prominent spokesperson for women in science.[9]
