What Happens After You Get In Touch

Three simple steps, direct to the science.

1

Our Scientists Read It

Your enquiry goes directly to our senior scientific team, not a sales queue. You’ll receive initial thoughts on the receptor biology and potential assay approaches.

2

Your Initial Discussion

We work through your objectives, timelines and deliverables based on your request, then develop an initial project proposal for you to take to your team.

3

Project Initiation

Once the project scope is agreed, projects typically initiate within two to four weeks, with regular communication throughout to keep you informed of progress.

“Excellerate scientists have become integral members of the wider project team, developing and running primary assays to an exceptionally high quality and providing their broader input across the project.”

Henry Danahay

Henry Danahay

Head of Biology, Enterprise Therapeutics

“As Enterprise Therapeutics, we have worked with Excellerate Bioscience since 2016. The team have enormous experience and have supported two of our drug discovery programs using a range of in vitro assays.

Most recently Excellerate scientists have become integral members of the wider project team, developing and running primary assays to an exceptionally high quality and providing their broader input across the project. The team are a pleasure to work with, communicating openly and showing great flexibility and proactivity to meet the needs of the project.”

Drug Discovery
Screening & Assay Services

Excellerate Bioscience provides high-quality in vitro pharmacology and drug discovery services to support preclinical research.

Based in Nottingham, UK, we partner with US biotech and pharmaceutical companies to deliver targeted assay development, robust pharmacological analysis, and collaborative scientific input across a range of therapeutic areas.

As a UK-based contract research organization (CRO), we offer streamlined study design, fast onboarding, and clear, decision-ready data aligned to your research goals. From proof-of-concept and mechanism-of-action studies to longer-term screening programs, we help US discovery teams move efficiently from idea to results.

For US clients, partnering with a UK CRO provides a practical advantage. Overlapping working hours across East and West Coast time zones allow studies to progress around the clock, with results often available before the US workday begins. Across multiple US biotech and pharmaceutical programs, we have delivered actionable data that supports faster timelines and more confident decision-making.

Scientific Capabilities Across Drug Discovery

Drug Discovery Phases

Target validation, hit identification, lead optimization, and preclinical decision support across early drug discovery.

Screening and Assay Development

Custom in vitro assay development and screening strategies optimized for robustness, reproducibility, and biological relevance.

Phenotypic and Functional Assays

Broad phenotypic and pathway-specific assays capturing functional cellular responses beyond target engagement alone.

Therapeutic Areas

Expertise across respiratory disease, immunology and inflammation, metabolic diseases, oncology, and CNS.

Targets, Modalities, and Molecular Pharmacology

GPCRs, kinases, enzymes, protein–protein interactions, and signaling pathways evaluated across small molecules, biologics, peptides, and emerging modalities using quantitative, functional, and kinetic pharmacology.

Data-Ready Assays

Assays designed with reproducibility, structure, and metadata in mind to support downstream analytics, modeling, and AI-driven discovery.

Why US Clients Choose Excellerate

1

Operational Reliability

We operate established processes for US-based clients, including international sample shipping and logistics, clear project scoping, and responsive communication. We use defined project workflows with regular check-ins, interim updates, and clear deliverables to support progression through to data delivery. Projects typically initiate within 2-4 weeks of proposal.

2

IP Security and Governance

All intellectual property remains with the client. We work under international standard CDAs and MSAs, with flexible contracting frameworks to align with your organizational legal and compliance requirements. Data are managed under strict confidentiality, using secure storage and encrypted data transfer as standard.

3

UK Scientific Expertise and Accountability

Our scientists bring deep expertise in pharmacology, cell biology, and assay development, supporting US discovery programs that require scientific ownership, reproducibility, and clear interpretation of complex data. We take accountability for study design, data quality, and scientific rationale, ensuring results, including structured datasets and metadata, are suitable for confident decision-making and downstream data-driven or AI-enabled analysis.

Scientific Leadership You Can Trust

Choosing Excellerate Bioscience means working with scientists who bring deep drug discovery experience and a clear understanding of how data informs decisions. Our leadership team combines academic rigor with industry perspective, ensuring studies are designed not just to generate data, but to answer the right scientific questions.

With specialist expertise in GPCR biology, cell-based pharmacology, and discovery screening, we work closely with US partners as an extension of their research teams. This collaborative approach adds scientific insight, helping programs progress efficiently while maintaining high standards of data quality, reproducibility, and interpretation.

Our focus is on delivering robust, decision-ready data that supports earlier and more confident go/no-go decisions, reducing risk and accelerating progression through the discovery pipeline.
