Vitronectin protein is widely used in stem cell culture. It provides a defined environment that supports the maintenance of pluripotency and is suitable for feeder-free culture, expansion, differentiation, and reprogramming of stem cells.

Qkine vitronectin is a high-purity animal origin-free recombinant protein with a molecular weight of 47.8 kDa. It is carrier-free and protein tag-free, ensuring exceptional lot-to-lot consistency and compatibility with translational studies and iPSC-based model production for screening. Qkine recombinant vitronectin protein is ultra high-purity with exceptionally low residual endotoxins making it suitable for the reproducible culture of stem cells, primary cells, organoids, and use in sensitive neural differentiations.

Our robust animal origin-free manufacturing platform, along with rigorous quality control procedures, ensures exceptional bioactivity and consistent performance from lot to lot, guaranteeing outstanding performance in your applications.
