Overview
Stem Cell Factor (SCF) is a cytokine-family protein that binds to the c-KIT receptor to regulate cell survival and proliferation. It plays an important role in hematopoiesis and promotes cell proliferation in combination with various growth factors. It also possesses physiological functions related to melanocyte and germ cell development. This recombinant SCF is produced through an E. coli expression system, offering high purity and stable activity for application in a wide range of research and formulation contexts.
Applications
- Hematopoiesis and stem cell research
- c-KIT signaling pathway studies
- Cell proliferation and survival research
- Mast cell function and immune-related studies
- Skin cell activation and regeneration formulations
- Pigmentation-related cell regulation (melanocyte)
- Scalp and hair-related functional formulations
