GMP Human SCF Protein (E. coli)

Product Details

SCF (Stem Cell Factor, also known as KIT ligand)​ is a critical growth factor for the survival, proliferation, and maintenance of HSCs and early progenitor cells. In HSC expansion, SCF is essential for preventing apoptosis and sustaining stemness in culture. In iPSC differentiation toward HSCs, SCF supports the transition from mesoderm to hematopoietic progenitors and enhances the emergence of CD34+ hematopoietic stem and progenitor cells.

Product Features and Advantages

1. Specific HSC Expansion Driver​: Efficiently supports hematopoietic stem cell expansion and hPSC-derived hematopoietic stem and progenitor cell differentiation, validated in multiple clinical trials and cell manufacturing processes.
2. Reliable Large-Scale Supply: Ensures batch production capacity, supporting robust and consistent manufacturing scale-up.
3. High Lot-to-Lot Consistency​: Ensures reliable and reproducible performance in every batch, supporting scalable applications.

GMP Platform Advantages

1. Quality Assurance: Global QMS with comprehensive and stringent QC release criteria.
2. End-to-End GMP Compliance: Full manufacturing and QC under a cGMP system.
3. Comprehensive Control of Adventitious Agents: Stringent biosafety from cell banks to final release.
4. Comprehensive Regulatory Support: Includes RSF and DMF to meet global requirements.
5. Resilient Supply Chain: Intelligent modular facilities ensure a stable global supply.
6. Professional Support: Extensive manufacturing and application expertise to accelerate development.
