The Problem with Wild-Type bFGF
Wild-type bFGF lasts only ~9 hours at 37°C, driving daily supplementation, cold-chain burden, higher dosing, shorter useful life, and higher media costs for researchers and clinicians alike.
Significantly improved stability
The Ultrastable™ bFGF
The most stable growth factor for regenerative medicine, cell culture and beyond.
Up to 10x higher intrinsic stability
Remains active for 21+ days at 37°C
About us
Phycin is advancing next-generation growth factors engineered for greater stability, performance, and reliability across regenerative medicine, cell culture, and related life science applications.
Our Solutions
Phycin solves the cost, consistency, and quality issues caused by unstable growth factors.
Ultrastable bFGF Performance
Stability Proven by Performance
Phycin’s Ultrastable bFGF Demonstrates Both Superior Stability and Potency
21-Day Activity Retention
Much stronger retention of functional activity after 21 days incubation at 37˚C, than WT and nearest competitor.
Higher Thermal Resilience
Substantial increase in melting temperature with respect to WT bFGF and nearest market competitor.
Freeze-Thaw Stability
Safe through 11+ freeze-thaw cycles, retaining functional activity and reducing variability during storage and use.
