Transcreener CD73 assay: Leveraging nucleotide detection to measure adenosine

BellBrook Labs delivers bespoke assay development and lead discovery solutions using its Transcreener® HTS platforms. Their expert team optimizes detection of small-molecule modulators for enzyme targets—tailoring buffer, enzyme, and detection conditions to yield strong initial-velocity signals (Z’ 0.7–0.9) in just 2–4 weeks.

The Transcreener® ADP² Kinase Assay Kit universally detects ADP produced by any kinase or ATPase using a direct mix‑and‑read format, eliminating coupling steps. Available in FP, FI, and TR‑FRET formats with far‑red tracers to minimize interference, it's HTS-ready across 96‑, 384‑, and 1536‑well plates with robust Z' ≥ 0.7 performance.

The Transcreener® AMP²/GMP² Phosphodiesterase Assay Kit directly detects AMP or GMP produced by PDEs, ligases, synthetases, ENPP1, and related enzymes using a mix‑and‑read FP or TR‑FRET format—no coupling steps needed. Compatible with 1–1000 µM native substrates, it delivers excellent HTS performance (Z’ ≥ 0.7, ≥100 mP shift) in a one-step, far‑red fluorescence assay.
