| 背景 | Stem cell factor receptor (CD117, the gene product of the c-kit proto-oncogene) and its ligand, stem cell factor (also named c-kit ligand, mast cell growth factor), play essential roles in gametogenesis, melanogenesis and hematopoiesis. The human stem cell factor receptor cDNA encodes a 972 amino acid (aa) residue precursor membrane protein with a 25 aa residue signal peptide (experimentally determined), a 495 aa residue extracellular domain, a 23 aa residue transmembrane segment and a 429 aa residue cytoplasmic domain. Stem cell factor receptor is a member of the type III subfamily of receptor tyrosine kinases (RTK) that also includes the receptors for M-CSF, Flt-3, PDGF, and VEGF. All class III RTKs are characterized by the presence of five immunoglobulin-like domains in their extracellular region and a split kinase domain in their intracellular region. SCF binding induces receptor homodimerization and signal transduction. SCF receptor is expressed in hematopoietic progenitor cells, normal B- and T-lymphocyte progenitor cells, mast cells, germ cells, melanocytes, neurons, glial cells, placenta, kidney, lung, and gut. In addition, SCF receptor expression has also been reported in a number of human tumor cell lines. SCF receptor can be proteolytically cleaved from the cell surface and high levels of soluble SCF receptor has been detected in cell conditioned medium and human plasma. Recombinant soluble SCF receptor binds SCF with high affinity and is a potent SCF antagonist. |

Cell Proliferation Induced by SCF/c‑kit Ligand and Neutralization by Human CD117/c-kit Antibody. Recombinant Human SCF/c‑kit Ligand (Catalog # 255-SC) induces cell proliferation in the TF‑1 human erythroleukemic cell line in a dose-dependent manner (orange line), as measured by the Resazurin (Catalog # AR002). Under these conditions, proliferation elicited by SCF/c‑kit Ligand is neutralized (green line) by increasing concentrations of Goat Anti-Human CD117/c-kit Antigen Affinity-purified Polyclonal Antibody (Catalog # AF332). The ND50 is typically 0.06-0.36 μg/mL in the presence of 20 ng/mL of Recombinant Human SCF/c‑kit Ligand. | |
CD117/c-kit in Human Brain. CD117/c-kit was detected in immersion fixed paraffin-embedded sections of human brain (hippocampus) using Goat Anti-Human CD117/c-kit Antigen Affinity-purified Polyclonal Antibody (Catalog # AF332) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to neurons.

Detection of Human CD117/c-kit by Western Blot. Western blot shows lysates of MO7e human megakaryocytic leukemic cell line. PVDF membrane was probed with 0.1 µg/mL of Goat Anti-Human CD117/c-kit Antigen Affinity-purified Polyclonal Antibody (Catalog # AF332) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for CD117/c-kit at approximately 150 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. | |
Detection of Human CD117/c-kit by Simple WesternTM. Simple Western lane view shows lysates of MO7e human megakaryocytic leukemic cell line, loaded at 0.2 mg/mL. A specific band was detected for CD117/c-kit at approximately 172 kDa (as indicated) using 5 µg/mL of Goat Anti-Human CD117/c-kit Antigen Affinity-purified Polyclonal Antibody (Catalog # AF332) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. |
