Human Flt-3/Flk-2 Antibody Summary
Accession # P36888
This antibody functions as an ELISA capture antibody when paired with Goat Anti-Human Flt‑3/Flk‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF812).
This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human Flt-3/Flk-2 DuoSet ELISA Kit (Catalog # DY812-05) for convenient development of a sandwich ELISA.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Human Flt‑3/Flk‑2 ELISA Standard Curve. Recombinant Human Flt‑3/Flk‑2 protein was serially diluted 2-fold and captured by Mouse Anti-Human Flt‑3/Flk‑2 Monoclonal Antibody (Catalog # MAB8121) coated on a Clear Polystyrene Microplate (DY990). Goat Anti-Human Flt‑3/Flk‑2 Antigen Affinity-purified Polyclonal Antibody (AF812) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (DY998) followed by Substrate Solution (DY999) and stopping the enzymatic reaction with Stop Solution (DY994).

The Flt-3 (fms-like tyrosine kinase) receptor, also named Flk-2 (fetal liver kinase) and Stk-1(stem cell tyrosine kinase) is a member of the class III subfamily of receptor tyrosine kinases that also includes KIT, the receptor for SCF and FMS, the receptor for M-CSF. The extracellular region of these receptors contains five immunoglobulin-like domains and the intracellular region contains a split kinase domain. Human Flt-3 cDNA encodes a 993 amino acid (aa) residue type I membrane protein with a 26 aa residue signal peptide, a 515 aa extracellular domain with 10 potential N-linked glycosylation sites, a 21 aa residue transmembrane domain and a 431 aa residue cytoplasmic domain. Mouse Flt-3 has also been cloned and shown to share 85% amino acid sequence identity with human Flt-3. Flt-3 expression has been detected in various tissues, including placenta, gonads, and tissues of nervous and hematopoietic origin. Among hematopoietic cells, the expression of Flt-3 was found to be restricted to the highly enriched stem/progenitor cell populations. The ligand for Flt-3 (FL) has been identified to be a transmembrane protein with structural homology to M-CSF and SCF. Recombinant soluble Flt-3/Fc chimeric protein has been shown to bind FL with high affinity and is a potent FL antagonist.
