RNA does not have the stability of the DNA double helix. To obtain the best results when dealing with RNA it is essential to start out with high-quality material and to carry out particularly careful quality control before and after processing. The so-called RIN (RNA Integrity Number) is an indicator of the quality of RNA. On a scale of 1–10, a RIN value of 1 indicates that the RNA is completely degraded and a RIN value of 10 that the RNA is fully intact. The higher the RIN number, the better the RNA quality. Wherever possible, material with high RIN numbers should always be used. https://www.leica-microsystems.com//science-lab/comparison-of-the-rna-quality-of-native-tissue-samples-with-tissue-samples-after-uv-laser-microdissection/ Sun, 30 Sep 2012 22:00:00 +0000 M.Sc., Cornelia Gilbrich-Wille https://www.leica-microsystems.com/5141 Digital Microscopy Quality Assurance Trends in Microscopy There are digital cameras, digital TV sets, digital picture frames, digital schools on the internet.
