背景 | Flt-3 Ligand, also known as FL, is an alpha -helical cytokine that promotes the differentiation of multiple hematopoietic cell lineages (1‑3). Mature mouse Flt-3 Ligand consists of a 161 amino acid (aa) extracellular domain (ECD) with a cytokine-like domain and a juxtamembrane tether region, a 21 aa transmembrane segment, and a 22 aa cytoplasmic tail (4‑6). Within the ECD, mouse Flt-3 Ligand shares 71% and 81% aa sequence identity with human and rat Flt-3 Ligand, respectively. Mouse and human Flt-3 Ligand show cross-species activity (4, 5, 7). Flt-3 Ligand is expressed as a noncovalently-linked dimer by T cells and bone marrow and thymic fibroblasts (1, 8). Each 36 kDa chain carries approximately 12 kDa of N- and O-linked carbohydrates (8). Alternate splicing and proteolytic cleavage of the transmembrane form can generate a soluble 30 kDa fragment that includes the cytokine domain (4, 8). Alternate splicing of mouse Flt-3 Ligand also generates a membrane-associated isoform with a 57 aa substitution following the cytokine domain (4, 5, 8, 9). Both transmembrane and soluble Flt-3 Ligand signal through the tyrosine kinase receptor Flt-3/Flk-2 (3‑6). Flt-3 Ligand induces the expansion of monocytes and immature dendritic cells as well as early B cell lineage differentiation (2, 10). It synergizes with IL-3, GM-CSF, and SCF to promote the mobilization and myeloid differentiation of hematopoietic stem cells (4, 5, 7). It cooperates with IL-2, -6, -7, and -15 to induce NK cell development and with IL-3, -7, and -11 to induce terminal B cell maturation (1, 11). Animal studies also show Flt-3 Ligand to reduce the severity of experimentally induced allergic inflammation (12). |

Cell Proliferation Induced by Flt‑3 Ligand and Neutralization by Mouse Flt‑3 Ligand Antibody. Recombinant Mouse Flt‑3 Ligand (Catalog # 427-FL) stimulates proliferation in BaF3 mouse pro‑B cell line transfected with mouse Flt‑3 in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse Flt‑3 Ligand (10 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse Flt‑3 Ligand Antigen Affinity-purified Polyclonal Antibody (Catalog # AF427). The ND50 is typically 0.05‑0.25 µg/mL. | |
Flt‑3 Ligand in HT‑2 Mouse Cell Line. Flt‑3 Ligand was detected in immersion fixed HT‑2 mouse T cell line using Goat Anti-Mouse Flt‑3 Ligand Antigen Affinity-purified Polyclonal Antibody (Catalog # AF427) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.
