Scientist – ELISA Assay Development
BioChek | Bracknell, Berkshire | Laboratory based

Help develop the next generation of veterinary diagnostic assays at BioChek’s new state-of-the-art facility in Bracknell.

Cranleigh STEM is partnering with BioChek to recruit a Scientist to join its Research & Development team. This is an opportunity for a scientist with practical assay development experience to take ownership of defined workstreams, from experimental design through to data interpretation and validation.

The role

You’ll develop, optimise and characterise ELISA assays, helping translate laboratory development into reliable, manufacturable diagnostic products.

Your responsibilities will include:

· Designing and optimising ELISA assays, including coating and blocking conditions, titrations and assay format selection.

· Performing and characterising antibody–enzyme conjugations, including HRP conjugation.

· Formulating assay buffers and reagents to improve performance.

· Analysing assay data, including curve fitting, sensitivity, specificity and precision.

· Planning experiments, troubleshooting assay performance and writing clear development reports.

· Supporting validation and technology transfer into production.

· Providing technical guidance to Research Associates and technicians.

About you

We’re looking for someone with:

· A BSc or MSc in immunology, biochemistry, microbiology or a related discipline.

· Hands-on assay development experience within a diagnostics or life science laboratory.

· Experience developing, optimising and troubleshooting ELISA assays.

· Practical knowledge of conjugation techniques and reagent formulation.

· Strong data interpretation skills, including curve fitting and statistical analysis.

· The ability to plan and deliver experiments independently while collaborating with colleagues.

Experience with GraphPad or JMP would be relevant, while basic R or Python skills would be an advantage. Familiarity with design controls, assay validation and veterinary diagnostic requirements would also be valuable.

Why join BioChek?

You’ll work in a new state-of-the-art facility, contribute to veterinary diagnostic product development and build your scientific expertise within an R&D team. The role offers a progression pathway towards Scientist II as your experience and capabilities develop.
