Our Technology

QCT Molecular Counting Platform

Our QCT (Quantitative Counting Templates) molecular counter technology uses specifically designed molecular standards that encode the molecular count information in sequencing data in a way that can be decoded using machine learning algorithms (4 US/PCT patents pending). This allows us to get extremely quantitative molecular counting information from any sequencing technology.
