FLT3LG Protein, Human (sf9, His)
Based on 1 Customer Validation
FLT3LG protein, a potent stimulator of early hematopoietic cell proliferation, activates FLT3 and synergizes with colony-stimulating factors and interleukins. As a homodimer, especially in isoform 2, it crucially promotes expansion and differentiation of hematopoietic progenitor cells. FLT3LG's collaborative signaling with other molecules underscores its significance in regulating hematopoiesis and maintaining hematopoietic system balance. FLT3LG Protein, Human (sf9, His) is the recombinant human-derived FLT3LG protein, expressed by Sf9 insect cells , with N-His labeled tag.
- Species: Human
- Source: Sf9 insect cells
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Description
FLT3LG protein, a potent stimulator of early hematopoietic cell proliferation, activates FLT3 and synergizes with colony-stimulating factors and interleukins. As a homodimer, especially in isoform 2, it crucially promotes expansion and differentiation of hematopoietic progenitor cells.

FLT3LG Protein, Human (sf9, His) is the recombinant human-derived FLT3LG protein, expressed by Sf9 insect cells , with N-His labeled tag.
Background
FLT3LG protein serves as a potent stimulator of early hematopoietic cell proliferation through the activation of FLT3, demonstrating synergistic effects when combined with various colony-stimulating factors and interleukins. This homodimeric protein, particularly in isoform 2, plays a crucial role in promoting the expansion and differentiation of hematopoietic progenitor cells. Its ability to activate FLT3 and collaborate with other signaling molecules underscores its significance in regulating hematopoiesis and maintaining the balance of the hematopoietic system.
Verified Bioactivity
Measured in a cell proliferation assay using BaF3 mouse proB cells transfected with mouse Flt3 and the ED50 is typically 2-11 ng/mL.

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of 20 mM Tris, 300 mM NaCl, 10% Glycerol, pH 7.5. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
