Specifications
| Product Data | |
| Species | Human |
|---|---|
| Expression Host | E. coli |
| Expression cDNA Clone or AA Sequence | |
| Predicted MW | 17.6 kDa |
| Purity | >98% by RP-HPLC, Anion-exchange FPLC, Silverstain |
| Presentation State | Purified |
| Buffer | Presentation State: Purified State: Lyophilized (freeze-dried) without stabilizer |
| Bioactivity | Biological: Human rh Flt3-ligand is fully biologically active when compared to standards. The ED50 range is 0.5-1.0 ng/ml corresponding to a specific activity of 1-2MUnits/mg, calculated by the dose-dependant stimulation of the proliferation of Human OCMI-AML5 cells. |
| Endotoxin | < 0.1 ng per µg (IEU/µg) of rh Flt3-Ligand |
| Reconstitution Method | Recombinant Flt3-Ligand is soluble in water and most aqueous buffers. Restore in water to a concentration not less than 0.1 mg/ml. This solution can then be stored at 2-8°C for future use or diluted into other buffered solutions. Further dilutions should be made into buffer containing carrier protein or medium containing serum. |
| Preparation | Lyophilized (freeze-dried) without stabilizer |
| Protein Description | Flt3-ligand produced in E. coli is a soluble non-glycosylated 17.6 kDa polypeptide containing 155 amino acid residues which comprises the extracellular domain of the transmembrane flt3-ligand protein. |
| Storage | Store lyophilized at 2-8°C for 6 months or at -20°C long term. After reconstitution store the antibody undiluted at 2-8°C for one month or (in aliquots) at -20°C long term. Avoid repeated freezing and thawing. |
| Stability | Shelf life: one year from despatch. |

| Summary | Dendritic cells (DCs) provide the key link between innate and adaptive immunity by recognizing pathogens and priming pathogen-specific immune responses. FLT3LG controls the development of DCs and is particularly important for plasmacytoid DCs and CD8 (see MIM 186910)-positive classical DCs and their CD103 (ITGAE; MIM 604682)-positive tissue counterparts (summary by Sathaliyawala et al., 2010 PubMed 20933441).supplied by OMIM, Jan 2011 |
