Plex Analysis

Example query: Which targets can overcome EGFR inhibitor resistance in NSCLC?

Plex queries billions of biomedical data points across genomics, proteomics, compound activity, and clinical trials using the Focal Graph knowledge graph.

Example result: Key resistance targets include MET amplification, KRAS G12C, and HER2/ERBB2 — with secondary mutations in EGFR T790M and C797S driving acquired resistance to first- and third-generation tyrosine kinase inhibitors (TKIs). Plex integrates genomic, proteomic, and Perturb-seq signatures to rank targets by evidence strength.

The Focal Graph visualizes relationships between targets (EGFR, KRAS, TP53, MET, HER2), compounds (Erlotinib, Sotorasib, Osimertinib, TKI, Trastuzumab), diseases (NSCLC, Adenocarcinoma), and pathways (T790M, C797S, PI3K) to surface evidence-backed insights for drug discovery.

How It Works

From data to discovery in three steps

01

Ask a question

Pose any scientific question — from target identification to biomarker discovery. Plex understands both biological and chemical context.

02

Plex searches the knowledge graph

Billions of data points spanning biology and chemistry — genomics, proteomics, compound activity, and clinical data — are integrated and scored in real time.

03

Get structured, actionable answers

Receive evidence-backed results with confidence scores, source citations, and built-in chemical intelligence tooling for structure-aware analysis.

Why Plex

Plex is not a literature search tool

Plex is a knowledge graph with an LLM for data and databases used in biomedical research.

While other tools search published text, Plex queries structured biological and chemical datasets — genomics, proteomics, compound activity, clinical trials — to deliver answers grounded in real data, not summarized literature.

—Literature-Based LLMs

  • Trained on text — searches literature, not data
  • No access to structured scientific databases
  • Generates plausible-sounding but unverifiable answers
  • Cannot query genomic, proteomic, or chemical datasets
  • No reproducibility — answers change with each query

vs

✓Plex: Data-First

  • Built on billions of structured data points from biomedical databases
  • Queries genomic, proteomic, clinical, and chemical datasets directly
  • Every answer traceable to specific data sources and records
  • Integrated chemical intelligence tooling for compound analysis
  • Reproducible, evidence-scored outputs ready for R&D decisions
