Pharma-Grade Bio-Analysis. Delivered on Startup Timelines.

Located at the heart of the life sciences community at Discovery Park, Kent, Tetrad Discovery is an agile, boutique Contract Research Organisation (CRO) specialising in pre-clinical bio-analysis, histology, and bespoke assay development.

We blend curiosity with cutting-edge technology to help you turn complex questions into clear, actionable answers. From early discovery to custom assay prototyping, our scientists work side-by-side with you to make breakthrough research easy and reliable.

Our Philosophy

We believe great discoveries happen when people connect, share ideas, and feel supported, so that’s exactly what we provide. Whether you’re bringing a new idea to life, launching a new product or solving an urgent technical challenge, we offer flexible services and friendly guidance every step of the way.

The Tetrad Advantage

We bridge the gap between innovative drug discovery and decision ready data. We understand that for early-stage biotechs and dynamic research teams, speed and reliability are everything.

• Bespoke Partnership: We don't believe in "one size fits all." We work collaboratively to design solutions that directly answer your specific biological questions.

• Unmatched Speed: Being boutique means we are fast. We bypass the heavy administrative delays of larger organisations to move rapidly from sample receipt to end of assay report submission.

• Pathologist-Guided Validation: Quality is our baseline. Our Immunohistochemistry and staining is overseen by senior experimental histopathologists with decades of Big Pharma R&D experience. We ensure your data is robust and built to withstand the intense scrutiny.

• High-Performance Biomarker Analysis: Utilising cutting-edge technology like the automated ELLA immunoassay system alongside traditional ELISA and Western Blotting, we deliver ultra-high sensitivity multiplex screening. We capture precise biomarker and PK/PD data while preserving your precious, limited samples.

Our Expertise

• Tissue & Pathology: Comprehensive histology, bespoke Immunohistochemistry (IHC) development, and spatial tissue validation to prove target engagement.

• Assays & Biomarkers: Biomarker analysis (ELISA, Magpix, Western Blot), ultra-sensitive ELLA Automated Immunoassays, and functional cell-based assays.

• Pharmacology Support: PK/PD assay optimisation tailored to your pre-clinical milestones.

Let's Connect

Whether you are a university, spin-out or an established biotech seeking specialised overflow capacity, we are here to support your journey from the bench to the clinic.
