Intended Use
The Heat Stable Recombinant Human bFGF Protein is an engineered variant of native bFGF. It retains the critical biological functions of:
• Supporting pluripotency in human embryonic stem cells
• Stimulating proliferation of mesoderm/ectoderm/endoderm-derived cells
• Promoting cell migration & angiogenesis
Key innovation: Enhanced thermal stability allows:
✓ Structural integrity across broad temperature ranges
✓ Sustained bioactivity under routine culture conditions
