Growth Factors
Cell Guidance Systems offers a wide selection of recombinant growth factors and cytokines in both standard and PODS® slow-release formats, to suit different cell culture applications.
Why are PODS® useful?
PODS® provide sustained release of the bioactive cargo protein (over periods >1 month) to generate a more constant environment for cells. PODS® may be placed in discrete positions on, or within, substrates or distributed evenly across a culture system. Consequently, PODS® technology addresses many of the issues of conventional recombinant proteins which are difficult to localize and quickly lose efficacy.
By creating a more stable environment, in-vitro and in-vivo, PODS® improve cell quality, enhance survival, differentiation, and maturation of cells.

Recombinant Growth Factors
In addittion to PODS® sustained-release growth factor technology, Cell Guidance Systems also provide a wide range of high-quality recombinant proteins for a variety of cell culture applications. Production expertise and rigorous quality control ensure excellent bioactivity and lot-to-lot consistency, so you can be assured that your growth factor is functional.
Why select recombinant proteins?
- Quality control: our growth factors are qualitatively and functionally tested. All the products have established acceptance criteria for biological assays, purity, and endotoxin levels.
- Bulk manufacturing: we manufacture our own proteins in our own laboratories in Cambridge, UK and we have the capability to scale up production to meet your needs.
- Documentation: you can request a certificate of analysis (CoA) for a specific lot before you buy it, where you will find specific ED50 (instead of “pass” or “fail”) and activity values for the functional biological assay. This way, you know exactly what you are buying. See an example and request your lot-specific CoA here.
- Consistency: all our lots are consistent as they follow strict acceptance criteria. Additionally, large production lots (including gram-scale) allow us to provide a steady inventory of the same lot number over time.
- Choice: our catalogue includes a wide range of human, mouse, and rat recombinant proteins.
- Value: our products are frequently benchmarked against leading brands. Request a personalized quote to receive a discount on your multi-product and bulk orders.
- Animal-Free option: produced without animal-derived materials. All processing and handling employ animal-free equipment and animal-free protocols.
- Multiple pack sizes: all our growth factors are available in four different pack sizes and we can also aliquot as per your requirements.
- Not in our catalogue? Please send an email to tech@cellgs.com with an inquiry about your protein of interest. We are continuously increasing our catalogue and we will let you know as soon as that growth factor is available.
