Legal

Most products require no additional agreements. Cell lines and certain biological materials require a Material Transfer Agreement (MTA) on first purchase from each supplier. We handle this digitally - both parties sign online before shipment. Subsequent orders from the same supplier proceed immediately.

XCeLL Factor™ IGF-1 LR3 is a recombinant insulin like growth factor designed to enhance proliferation, differentiation, and survival in mammalian cell systems. The LR3 analog incorporates a thirteen amino acid extension at the N terminus, which reduces binding to inhibitory proteins and increases its effective activity in serum free media. This extended signaling capability supports myoblast proliferation, protein synthesis, and early differentiation processes relevant to cultivated meat and advanced tissue culture applications.

The protein is produced through E. coli expression and purified to a high level of homogeneity with low endotoxin content. Each batch is manufactured to preserve structural integrity and maintain consistent biological activity across a range of cell types, including fibroblasts and myocytes. This defined and animal origin free production approach contributes to predictable performance in workflows where reproducibility and quality control are required for media optimization or early scale up.

XCeLL Factor™ IGF-1 LR3 is supplied as a liquid formulation that integrates directly into serum free or chemically defined media. The format supports stable storage at low temperature and reduces preparation time by eliminating reconstitution steps. Once added to culture systems, the growth factor provides sustained signaling that promotes viable expansion and supports the development of tissue specific characteristics.

This product is suitable for R&D and early process development in cultivated meat, regenerative culture systems, and general mammalian cell applications where defined anabolic signaling is required to support reproducible outcomes.

    DMEM vs F12 for Cultivated Meat Cell Lines

    For cultivated meat R&D teams, I’d screen DMEM, Ham’s F12 and a 1:1 DMEM/F12 mix before choosing a basal medium. None is complete on its own: your cell line, supplements...
