Why use RNAscope ISH?

Most discovery tools and standard transcriptomic techniques such as qPCR and sequencing that are gold standard molecular methods for disease profiling, rely on dissociated cells which results in a loss of spatial information.

Inspired to solve these challenges, ACD scientists revolutionized the RNAscope™ assay, a novel multiplex nucleic acid in situ hybridization technology. ACD's unique patented probe design amplifies target-specific signals but not background noise, delivering clear and actionable results with high sensitivity and specificity.
