Qkine's food-grade species-matched FGF-2 discovery kit provides recombinant FGF-2 variants derived from bovine, porcine, chicken, and fish sequences for comparative evaluation in cultivated meat applications. The kit enables researchers to assess the performance advantages of species-matched growth factors, which deliver superior receptor binding efficiency and cellular responses compared to heterologous proteins, allowing optimization of FGF-2 selection based on target cell line and production economics.
All proteins in this food-grade discovery kit are produced as recombinant proteins in E. coli or mammalian cell expression systems and purified to >95% purity by SDS-PAGE quantitative densitometry. Manufactured in the UK under a HACCP food manufacturing regime, each protein is animal-origin-free (AOF), carrier protein-free, and tag-free to ensure exceptional purity and lot-to-lot consistency. Comprehensive quality control includes mass spectrometry verification, bioactivity testing with EC₅₀ determination, endotoxin analysis (<0.05 EU/μg), and full traceability documentation including certificates of analysis, certificates of origin, allergen analysis, and beta-lactam-free certification.
The kit components are supplied lyophilized for extended shelf life and should be reconstituted according to the certificate of analysis recommendations provided with each protein. Suitable for cultivated meat media optimization, process development, empirical testing of growth factor performance, and cost-benefit analysis during formulation design. This food-grade discovery kit is manufactured to support novel food regulatory submissions, commercial manufacturing requirements, and scale-up to production volumes.
