Human FGF basic Superior Stable Mutant Protein, premium grade

Our Recombinant Human FGF basic Superior Stable Mutant Protein, developed via an AI-modified and experimentally validated closed-loop efficient protein design platform, is the optimal FGF2 mutant with superior thermal stability and activity compared to wild-type FGF2, making it more suitable for various stem cell culture processes. This reduces medium replacement frequency, lowers contamination risks from frequent operations, and saves costs/time for stem cell culture by minimizing reagent consumption and labor, especially in large-scale applications. This product is designed and developed utilizing our proprietary AI technology, which is protected by patent rights. We retain full commercial rights to this product.

It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

• Engineered via a Closed-Loop AI Design Platform – Enables rational sequence optimization to achieve maximal functional performance.
