XCeLL Factor™ EGF

XCeLL Factor™ EGF is a recombinant human epidermal growth factor formulated to support rapid proliferation and controlled differentiation in epithelial and fibroblast cell systems. It provides a defined signalling input for serum free and xeno free culture environments, making it a useful component in media formulations designed for cultivated meat research and broader mammalian cell expansion. Its activity helps maintain viability and promotes organised cell growth in workflows where serum components must be removed for reproducibility and regulatory alignment.

The protein is manufactured through E. coli expression and purified to a high level of homogeneity, with endotoxin levels maintained below accepted thresholds for sensitive culture systems. This production approach delivers consistent batch performance and removes the variability associated with animal derived sources. Its defined structure and reliable biological activity support predictable responses in cell types commonly used in tissue development, culture maintenance, and early scale up processes.

XCeLL Factor™ EGF is supplied as a liquid formulation designed for integration into chemically defined and serum free media. The format supports stable storage at low temperature and eliminates reconstitution requirements, allowing rapid preparation of stock solutions and direct incorporation into basal media or supplement blends. Once added to culture systems, it supports reproducible proliferation and tissue specific behaviour under defined conditions.

This growth factor is suited to R&D and early process development for cultivated meat, epithelial biology, and general mammalian cell culture where controlled and traceable signalling inputs are required for consistent outcomes.
