Mucosubstances in the porcine gastrointestinal tract: Fixation, staining and quantification [PDF]

, 2019
Mucins are of great interest in intestinal research and histochemical methods are often employed to identify them. Since it is in the nature of mucins that they are “hard to hold onto” once they come into contact with water, a frequently used medium in ...

The Paraffin-Embedded RNA Metric (PERM) for RNA Isolated from Formalin-Fixed, Paraffin-Embedded Tissue [PDF]

BioTechniques, 2016
RNA isolated from formalin-fixed, paraffin-embedded (FFPE) tissue is commonly evaluated in both investigative and diagnostic pathology. However, the quality of the data is directly impacted by RNA quality. The RNA integrity number (RIN), an algorithm based on a combination of electrophoretic features, is widely applied to RNA isolated from paraffin ...
