GMP Human Flt-3 Ligand Protein

FLT3L (Fms-related tyrosine kinase 3 ligand)​ is a key cytokine that supports the proliferation, survival, and maintenance of early hematopoietic progenitors and dendritic cells. In HSC expansion systems, FLT3L promotes the self-renewal and output of multipotent progenitors. In iPSC-to-HSC differentiation protocols, it acts in the early hematopoietic specification stage to support the emergence of hemogenic endothelial cells and subsequent hematopoietic progenitor formation.

• 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.
• Reliable Large-Scale Supply: Ensures batch production capacity, supporting robust and consistent manufacturing scale-up.
• High Lot-to-Lot Consistency​: Ensures reliable and reproducible performance in every batch, supporting scalable applications.

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