The BaseScope™ Duplex Assay is based on ACD’s patented signal amplification and background suppression technology.  The BaseScope™ assay leverages the same platform of the proven and established RNAscope® technology but expands the detection capabilities, enabling the detection of short RNA target sequences and exon junctions in cells and tissues with morphological context, thereby providing new data dimensions and unique insight into biological mechanisms.The BaseScope™ Duplex Assay can be used for simultaneous visualization of two RNA targets while maintaining single cell resolution.

Applications of the BaseScope™ Duplex Assay include:

Discerning bi-allelic vs. mono-allelic CRISPR-mediated mutations
Co-detection of circRNAs and linear RNAs
Simultaneous visualization of 2 splice variants or short targets
Profiling expression of a splice variant, short target, or gene edit in a cell-specific manner
One major application for the BaseScope™ Duplex Assay is to identify gene edits in specific cell populations by duplexing RNA ISH cell marker probes and edit-specific probes.  The BaseScope™ Duplex assay can discern if the CRISPR/Cas9-mediated mutation is mono- or bi-allelic with duplex of WT and edited probes.

BaseScope™ Duplex Reagent Kit provides reliable results which are ideal for archiving due to the permanent staining visible under any standard bright field microscope. The BaseScope™ Duplex Reagent Kits are designed to provide more intense staining when low copy target gene expression is anticipated (1–20 copies per cell). The BaseScope™ Duplex reagent kits are compatible with BaseScope™ probes.
