To compare untreated tissue samples with fixed and stained tissue samples, three cryo-asserved murine brains of known RNA integrity (RIN) were used. After cryo-asservation at –80 °C, these were transferred to a cryomicrotome and incubated at –35 °C for 45 min. Then the tissue was equilibrated at –18 °C for 30 min and cut into 12 µm sections at –18 °C by …
There are digital cameras, digital TV sets, digital picture frames, digital schools on the internet. Cryptologists design digital signatures, communication researchers speak of digital identity. Digital may be an overused buzzword, but digital technology has undeniably revolutionized our world ever since the invention of the computer and will continue to do so in future. The …
One of the main features of a digital microscope is the speed and ease with which it enables surface models to be created of macroscopic and microscopic structures. In a qualitative evaluation, these provide a better understanding and a more detailed documentation of the specimen. In addition, quantification of the surface provides valuable information about …
