Abstract
Specific chromogen- and fluorescence-based detection of microRNA by in situ hybridization (ISH) in formalin-fixed and paraffin-embedded (FFPE) tissue sections has been facilitated by locked nucleic acid (LNA)-based probe technology and can be performed within a single working day. In the current method paper, we present a similar simple 1-day ISH method developed for cryostat sections obtained from clinical cryo-embedded tissue samples. The presented chromogen-based ISH method does not involve proteolytic pretreatment, which is mandatory for FFPE sections, but still retains a sensitivity level similar to that obtained in FFPE sections. The LNA-based ISH method is not only applicable in situations where only access to cryo-embedded material is possible, but it also has a potential use if combining microRNA ISH with immunohistochemistry in double fluorescence staining with antibodies not being compatible with proteolytic predigestion.Entities:
