Flt-3 Ligand BioAssay(TM) ELISA Kit (Mouse)

Fms-related tyrosine kinase 3 ligand(FLT3LG), also known as Flt-3ligand or FL, is a protein which in humans is encoded by the FLT3LG gene. It is mapped to 19q13.3. Flt-3ligand is a hematopoietic four helical bundle cytokine. It is structurally homologous to stem cell factor(SCF) and colony stimulating factor 1(CSF-1). In synergy with other growth factors, Flt-3ligand stimulates the proliferation and differentiation of various blood cell progenitors. Besides that, Flt-3ligand can control the development of Dendritic cells(DCs) and is particularly important for plasmacytoid DCs and CD8-positive classical DCs and their CD103-positive tissue counterparts. Flt-3ligand also can enhance the response of stem and primitive progenitor cells to other growth factors to generate all myeloid lineages except erythroid cells. Sample Type: Cell culture supernates and serum. Intended Use: For quantitative detection of mouse Flt-3ligand in cell culture supernates and serum. Sensitivity: <10pg/ml, Range: 31.2-2000pg/ml, Specificity: Natural and recombinant mouse Flt-3ligand, Test Principle: This mouse Flt-3ligand BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for Flt-3ligand has been precoated onto 96-well plates. Standards (NSO) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Flt-3ligand is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse Flt-3ligand amount of sample captured in plate.
