We use liquid chromatography and mass spectrometry instruments (LC-MS) at all levels of pre-clinical research, clinical development, and product delivery.
These arrays instruments are uniquely configured to meet our specific needs, combined with proprietary standards and calibrators to deliver accurate, reproducible glycopeptide analyte identification and quantification.
Peak Integration Platform (PIP) is a software that translates the complex output of the LC-MS instrument - into easily interpretable, digital data. It is powered by artificial intelligence and recurrent neural networks and was trained on a massive collection of manually-annotated chromatographic peaks.
It reduces the time required to interpret chromatograms from months to minutes, and, for the first time, has allowed glycoproteomic research to scale to meet the requirements of clinical studies.
We apply deep learning on the backend of our data pipeline to efficiently process LC-MS output in a very short amount of time. This ranges from spectral identification and retention time prediction during biomarker discovery to peak selection and quantification in our targeted panels. These applications are possible because of the large amount of data generated from mass spectrometry experiments. We employ open source formats which make the trained neural networks (specific to a particular problem) highly reproducible.
Once the data are wrangled into per-glycoform, per-patient expression, however, we are looking at much smaller pieces of data (hundreds of patients by ~1000 biomarkers). This context is not appropriately powered to generate deep learning models that will validate in independent data; thus, all of our classifiers to-date employ traditional statistical models and cross-validation rather than deep learning. In other words, we do not input our biomarkers into a “black box” to output a diagnosis on the other end.
