Qkine Food-grade B8 Media Discovery Kit

Qkine's food-grade B8 media discovery kit delivers eight core recombinant growth factors for pluripotent stem cell maintenance and differentiation in cultivated meat applications. The kit supports development of chemically defined, animal-origin-free media formulations for induced pluripotent stem cells and embryonic stem cells, providing the essential signalling molecules required for self-renewal, directed differentiation, and lineage specification in serum-free culture systems.

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.
