Biomarker and Bioanalytical Solutions To De-Risk and Advance Your Therapeutic Pipeline
Global Scientific Excellence
Partner with a leading biomarker and bioanalytical lab clinical research organisation (CRO) that combines specialist scientific expertise with a collaborative approach. Our 120+ scientists across 3 global laboratories integrate seamlessly into your team, bringing over two decades of experience in developing, validating, and delivering complex, custom-designed assays to support your path from discovery through to regulatory submission.
About Synexa Life Sciences
Synexa Life Sciences is a biomarker and bioanalytical lab clinical research organisation (CRO), specialising in the development, validation and delivery of a wide range of complex and custom-designed assays.
With a team of over 200 staff across three global laboratory locations; Manchester, Turku (Finland) and Cape Town, we provide innovative solutions to support our customers to achieve their clinical milestones.
Our main areas of expertise include biomarker identification and development, large and small molecule clinical bioanalysis, (soluble) biomarker analysis (utilising MSD, LC-MS/MS, ELISA, RIA, fluorescence and luminescence-based technologies), cell biology (including flow cytometry, ELISpot and Fluorospot) and genomic services to support clinical trials and translational studies.
We pride ourselves on our deep scientific expertise and ability to tackle complex problems, translating them into robust and reliable assays to support clinical trial sample analysis.

Our Services
Reduce clinical trial risk by validating your therapeutic’s biology in human disease models. We generate mechanistic data from fresh patient samples that predicts clinical response, guides biomarker strategy, and strengthens regulatory submissions before you enter the clinic.
Your biomarker strategy determines what data you collect and what regulatory questions you can answer. We develop custom biomarker panels that measure what matters: target engagement, pathway modulation, disease activity, and the clinical signals that drive development decisions from Phase I through approval.
Accelerate your bioanalysis with precise LC‑MS/MS quantification of small molecules, peptides, proteins, and ADCs. Our dedicated 16,500 sq ft UK facility delivers rapid, ICH M10‑validated PK, TK, and biomarker analysis from discovery through clinical development, with the GLP/GCP compliance and turnaround speed your programmes require.
Developing large‑molecule biotherapeutics requires sensitive, validated immunoassays you can trust. We design bespoke ligand‑binding assays for PK, ADA, and biomarker quantification, delivering the precision and GCP/GLP compliance needed for confident regulatory decision‑making.
From immunophenotyping rare cells to measuring target engagement and immune function, our custom flow cytometry panels deliver validated, high‑parameter analysis. Designed to CLSI H62 standards and tailored to your endpoints, our assays provide the reproducible cellular insights that guide therapeutic development decisions.
Measure antigen‑specific immune responses at single‑cell resolution. Our GCLP‑compliant ELISpot assays detect low‑frequency T‑cell and B‑cell responses critical for vaccine development, immunotherapy monitoring, and CAR‑T assessment. From custom assay design to data analysis, we deliver the sensitive, validated cytokine detection your immune monitoring trials depend on.
GLP toxicology studies require verified dose formulation concentrations. Our Manchester facility verifies formulation accuracy and stability, ensuring regulatory submissions meet requirements. We validate concentration, consistency, and shelf‑life using proven analytical methods.
