For in vitro use only!

Shipping: shipped at ambient temperature

Storage Conditions: store at -20 °C
avoid freeze/thaw cycles

Shelf Life: 12 months

Molecular Weight: 16.4 kDa

Accession number: P49772

Accession number: P49772

Purity: > 95 % (SDS-PAGE, RP-HPLC)

Form: lyophilized

Solubility: It is recommended to reconstitute the lyophilized FLT3 in sterile bidest H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Activity: The activity is determined by the ability to generate CD11c+ splenic dendritic cells in vivo in C57B1/6-12 week female mice. To obtain the desired affect, mice were treated with approximately 25 μg of FLT-3 Ligand once daily for 9 consecutive days via intraperitoneal injection.

Description:
Recombinant murine FLT3 Ligand produced in E. coli is a non-glycosylated, polypeptide chain containing 144 amino acids and having a molecular mass of 16.4 kDa. FLT3 ligand is a receptor for the fl cytokine has a tyrosine-protein kinase activity & a growth factor that regulates proliferation of early hematopoietic cells. Flt3-Ligand synergizes with other CSFs and interleukins to induce growth and differentiation. Recombinant FLT3 Ligand is purified by proprietary chromatographic techniques.

Amino Acid Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Thr-Gln-Asp-Cys-Ser.
