Research Solution: Preclinical safety assessment and animal model studies
Preclinical drug safety assessment in animal models is well established as a routine part of pharmaceutical drug development to evaluate the potential safety issues associated with novel therapeutic targets and corresponding lead molecules. Immunohistochemistry (IHC) is the method of choice for assessment of targets and toxicity-related biomarkers. However, systematic application of IHC is hindered by inconsistent performance of commercial antibodies, time-consuming antibody development and validation and general lack of reagents for some animal models.
The RNAscope™ technology enables detection of almost any RNA biomarker with single-molecule sensitivity and high specificity in formalin-fixed paraffin-embedded (FFPE) tissues. It provides a fast, efficient and universal solution to characterize tissue distribution of drug target and biomarker expression in a highly specific and sensitive manner.
ACD Drug Safety Assessment Study
ACD conducted a study using 25 FFPE tissues (provided by Pfizer, Inc.) from 3 species (cynomolgus monkey, dog and rat) to:
- Identify the optimal pretreatment conditions for different tissues in different species
- Identify positive control probe for each tissue
- Detect specific RNA markers (cell-type, proliferation and apoptosis biomarkers)
These results show the utility and efficiency of RNAscope as a platform for target and safety marker assessment in preclinical animal studies.
