PictorLabs provides AI-powered virtual staining that converts a single unstained tissue sample into multiple diagnostic-equivalent virtual stains, preserving tissue and speeding analysis. The company uses proprietary deep-learning models (DeepStain™ and ReStain™) to generate unlimited virtual histological and biomarker stains that replicate standard chemical stains in minutes. Its platform is positioned as a digital pathology solution for drug discovery, biomarker screening, research laboratories, contract research organizations, and clinical workflows. The technology reduces chemical waste and tissue consumption while enabling higher-throughput pathology and easier deployment of digital workflows. PictorLabs partners with biopharma, CROs, and clinical laboratories to advance digital pathology and diagnostic testing.
