What We Develop

🧪

Serum-Free Media

Replace FBS with a defined, reproducible formulation. Retain performance while gaining regulatory compliance, simplified downstream processing and supply chain security.

Any mammalian cell lineResearch to GMP
⚗️

Chemically Defined Media

All components identified at known concentrations. Maximum batch-to-batch consistency and full regulatory transparency for BLA, MAA and IMPD submissions.

CHO, HEK293, VERO, hybridomaGMP preferred
🌿

Xeno-Free Media

Human-derived or recombinant components only — no non-human animal materials. Required for cell therapy products intended for clinical use and ATMP manufacturing.

T-cells, MSCs, NK cellsCAR-T, regenerative medicine
🔬

Feed Supplements

Concentrated feed supplements matched to your basal medium. Optimised for fed-batch and perfusion processes to extend culture duration and improve titre.

Inhibitor Cocktails

Custom small molecule inhibitor supplements formulated to your exact concentrations — supplied as separate vials for protocol flexibility. Validated for stem cell, organoid and DMPK applications.

Development Process

01

Consultation

Define your cell line, application, target performance specs and regulatory requirements. We assess feasibility, component sourcing and timeline.

Week 1
02

Formulation Design

Base medium selection, DoE-based nutrient screening, amino acid and lipid optimisation targeting your specific cell line and process parameters.

Weeks 2–6
03

Testing & Validation

Growth kinetics, cell viability, productivity, product quality (glycosylation, aggregation) and stability assessment across multiple passages.

Weeks 6–12
04

Scale-Up

Transfer from bench to bioreactor scale with process characterisation. Performance verification at target production scale.

Weeks 12–16
05

GMP Production

Commercial manufacturing with full batch documentation, CoA, CoO, stability data. Ongoing supply with batch reservation available.

Month 4–6+

What We Offer

Flexible Batch Sizes

500 mL for early development through to 1000+ litres for commercial supply. No minimum order quantity for standard formulations.

Liquid & Powder

Ready-to-use liquid or dry powder for extended shelf life and reduced cold-chain cost. Custom packaging and aliquot sizes available.

Full Documentation

CoA, CoO, sterility certificate, endotoxin report, osmolality, pH — all included. DMF support available for regulatory submissions.

NDA-Protected Formulation

Your formulation remains confidential. We produce under signed NDA with full IP protection for client-proprietary recipes.

Batch Reservation

Reserve validated production lots for up to 6 weeks at no prepayment cost — ensuring lot continuity for long-running research or manufacturing programmes.

Technical Support

Dedicated project manager and scientific support throughout development, adaptation, scale-up and commercial supply phases.

Frequently Asked Questions

How long does custom media development take?

Simple modifications to an existing formulation take 2–4 weeks. Full custom development from scratch takes 8–16 weeks depending on cell line and complexity. GMP-grade production with complete documentation takes 3–6 months. A detailed project plan is provided at project start.

What volumes can you supply?

From 500 mL for initial research and development through to 1000+ litres for commercial production. Both liquid and dry powder formats are available. Multi-year supply agreements with volume commitments are available for commercial customers.

Can you reproduce a media formulation we already have?

Yes — we can reproduce existing formulations including licensed academic recipes (such as HENSM/NaivaCore), client-developed recipes, or modifications of commercial basal media. We handle all sourcing and QC under NDA.

Do you offer GMP-grade custom media production?

Yes. We produce under ISO 9001 and ISO 13485 conditions with GMP-compatible manufacturing capability. Full regulatory documentation is included — CoA, CoO, stability data, sterility and endotoxin certificates. DMF/ASMF support is available for regulatory submissions.
