BaseScope analysis using the HALO ISH module. (A) PPIB positive control shown with HALO mark-up image in (B). (C) KRAS assay shown with mark-up in (D). In the mark-up images, cells with probes are shown in varying shades of green with darker cells having more probes. White cells have no probes or a number below the minimum number defined by the user.

Duplex FISH assay analyzed with the FISH module of HALO. (A) Duplex FISH assay with nuclei in blue, probe 1 in green, and probe 2 in magenta. (B) HALO FISH analysis mark-up image, where cyan nuclei represent cyan probe positivity and cyan spots represent probes. Similarly, green nuclei represent green probe positivity and green spots represent the green probe. Purple nuclei represent dual positivity.

Co-detection assay using the ISH-IHC module of HALO. (A) ISH-IHC assay with a magenta probe and a teal protein biomarker. (B) HALO mark-up image where blue represents nuclei without probe and lime green represents positivity for the teal IHC biomarker. The pink spots represent the magenta probe, and the gray rings represent a user defined maximum cytoplasmic radius.

ACD has partnered with Indica Labs to offer quantitative RNAscope image analysis. This advanced digital pathology image analysis solution brings objective and accurate quantification to RNA in situ hybridization, enabling a new generation of applications based on single-cell analysis. With the ISH, ISH-IHC, FISH, and FISH-IF modules of the HALO® image analysis platform, pathologists and researchers can perform quantitative gene expression analysis at single-cell resolution and interpret data in the histopathological context

RNAscope quantification with HALO provides:

  • Quantitative and reproducible RNAscope spot counting
  • Single-plex and multiplex ISH quantification
  • Brightfield and fluorescent ISH quantification
  • Cell-by-cell expression profiles
  • Automatic generation of H-scores and histograms
  • Rapid whole-slide analysis
  • Manual and automatic selection of distinct cell populations
  • Proximity Analysis, Nearest Neighbor Analysis, Infiltration Analysis, and Density Heatmap are available with the Spatial Analysis module
