CPS1 Serum Immunoassay: What a Mitochondrial Enzyme Biomarker Tells You That ALT Cannot

Carbamoyl phosphate synthetase 1 (CPS1) is a hepatocyte-selective mitochondrial enzyme with a serum half-life of roughly 126 minutes, making it a near-real-time indicator of injury trajectory rather than injury presence. A 2026 Gut review synthesizes a decade of mechanistic and clinical work, including ELISA data from 764 serial samples across 270 acute liver failure patients, establishing CPS1 as a prognostically informative complement to standard aminotransferase panels. All AlpinaBioTech CPS1 immunoassay products are for Research Use Only.

Fortrea Acquires Worldwide Clinical Trials' Bioanalytical Lab: What the $45 Million CRO Deal Means for Assay Scientists

On September 2, 2026, Fortrea announced a $45 million all-cash acquisition of Worldwide Clinical Trials' Early Phase Services division, bringing a 60,000-square-foot GLP bioanalytical laboratory and a 200-bed GCP clinical pharmacology unit under one operational roof. For assay scientists running PK and immunogenicity programs, the deal changes the vendor map by eliminating inter-organization hand-offs between sample collection and bioanalytical processing. Broader CRO consolidation and pending FDA biosimilar guidance shifts make integrated bioanalytical infrastructure increasingly valuable for early-phase biologic programs.

Adalimumab Biosimilar Switches in Pediatric IBD: What the Trough Level Drop Means for Your Monitoring Protocol

Two 2026 multicenter studies confirm that nonmedical adalimumab biosimilar switches in children with IBD generally maintain disease control, but trough levels fell significantly post-switch in one cohort, and neither study included systematic TDM or ADA testing. This article examines what that measurement gap means for laboratory monitoring protocols around pediatric biosimilar switches.
