Qkine's food-grade serum-free media optimization discovery kit provides a comprehensive set of recombinant growth factor variants for systematic evaluation in cultivated meat cell culture workflows. The kit enables rapid empirical assessment of protein performance across multiple species and formulations, helping researchers identify optimal growth factor combinations for cell proliferation, differentiation, and maintenance while reducing trial time and development costs during media design.
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.
