Flt‑3 Ligand, also known as FL, is an alpha -helical cytokine that promotes the differentiation of multiple hematopoietic cell lineages.Stimulates the proliferation of early hematopoietic cells by activating FLT3. Synergizes well with a number of other colony stimulating factors and interleukins. FLT3 Ligand Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with C-hFc tag. The predicted molecular weight is 44.8 kDa and the accession number is P49771-1.

| Expression System | HEK293 Cells |
| Tag | C-hFc |
| Accession Number | P49771-1 |
| Synonyms | SL cytokine,FLT3LG,Flt3L,Flt3 ligand,FL |
| Construction | Thr27-Pro185 |
| Protein Purity | > 95% as determined by Tris-Bis PAGE |
| Molecular Weight | 44.8 kDa (predicted). Due to glycosylation, the protein migrates to 90-118 kDa based on Tris-Bis PAGE result. |
| Endotoxin | < 1 EU/μg by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, a mixture containing 8% trehalose and 0.01% Tween is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, Lyophilized powders are shipping with blue ice. |
