Labels on slides together with corresponding lists on cards or sheets build what is here called a specific finding system. In the sciences of the archive (Daston) the disciplinary memory together with such a finding system are the basis to the ability of the sciences today to reactivate ...
In fluorescence microscopy, co-localization refers to the spatial overlap between different fluorescent labels in cells. The degree of overlap between two or more channels in a microscope may reveal a physical interaction or topological functional interc
Routine (or H&E) and special stains allow us to visualize otherwise transparent tissue under a microscope and are critical for tissue-based diagnosis. Lean More Processing Fatty Specimens One of the most critical steps in histology is fixation, especially when it comes to fatty tissue. ...
an advance that he believes will happen later this year; both Zeiss and Leica are reported to have licensed the technology last year. But, as an example from fluorescence microscopy shows, the spread of a technology can be slow. The first commercial multiphoton microscope was introduced...
The signal was verified and imaged using the Leica SP8 inverted confocal microscope (Leica Camera AG, Wetzlar, Germany) with the TMR (red, fluorescence excitation lasers at Ex 542 nm, Em 572 – 759 nm for TMR peptides) and DIC channels at 20×g at 0.96 µm steps. Images were ...
Another, Manu Prakash, has become a pioneer in frugal innovation, famous for (among many other things) his 50-cent microscope that’s been distributed in the millions. One of the students, Amon Millner, coinvented the Scratch programming language that’s been used by millions of kids; ...
We, thus, collected sets of images (z-stacks) of the same microscope field from several planes at equidistant intervals along the z axis and centered at the plane that was most in-focus for the majority of the cell bodies. During collection, the microscope stage was kept fixed in x and ...
on Firing Range. Afterwards, we decided to write a rap parody of the song "Bringing Sexy Back" by Just Timberlake. The song was named "Bringing Hatchet Back" and we sang it late into the night on our console 其中一最佳的片刻在义务电话是朋友和我在一次网上比赛得到了许多柴刀杀害在射击距离...
Be wowed by how they perform. Even the coldest conditions didn't affect on the printed image on the label. Freezer No visible effects when applied to glass test tubes with a gap, polypropylene tubes/vials with a gap, glass microscope slides, large and small straws, flat polypropylene, alumin...
On a TEM/STEM equipped with a LaB-6 filament the smallest labels that are detectable are 1-2 nm. Efficient detection of ultra-small labels requires a field emission microscope.Related ReferencesOtten, M.T. 1991: High-angle annular dark-field imaging on a TEM/STEM system Journal of Electron...
