Rat

This assay has high sensitivity and excellent specificity for detection of SCF. No significant cross-reactivity or interference between SCF and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between SCF and all the analogues, therefore, cross reaction may still exist in some cases.

Store all reagents at 2-8 degree C.

Assay Type: Competitive or Sandwich. Samples: Serum, plasma, Cell Culture Supernatants, body fluid and tissue homogenate. Sensitivity: 1.0 pg/mL.

Intended Uses: This SCF ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Rat SCF. This ELISA kit for research use only, not for therapeutic or diagnostic applications!

Cell Biology

Principle of the assay: SCF ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with a monoclonal antibody specific for SCF. Standards or samples are then added to the microtiter plate wells and SCF if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount of SCF present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated polyclonal antibody, specific for SCF are added to each well to "sandwich" the SCF immobilized on the plate. The microtiter plate undergoes incubation, and then the wells are thoroughly washed to remove all unbound components. Next, substrate solutions are added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain SCF and enzyme-conjugated antibody will exhibit a change in color. The enzyme-substrate reaction is terminated by addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The SCF concentration in each sample is interpolated from this standard curve.

This gene encodes the ligand of the tyrosine-kinase receptor encoded by the KIT locus. This ligand is a pleiotropic factor that acts in utero in germ cell and neural cell development, and hematopoiesis, all believed to reflect a role in cell migration. In adults, it functions pleiotropically, while mostly noted for its continued requirement in hematopoiesis. Two transcript variants encoding different isoforms have been found for this gene.

SCF: Ligand for the receptor-type protein-tyrosine kinase KIT. Plays an essential role in the regulation of cell survival and proliferation, hematopoiesis, stem cell maintenance, gametogenesis, mast cell development, migration and function, and in melanogenesis. KITLG/SCF binding can activate several signaling pathways. Promotes phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, and subsequent activation of the kinase AKT1. KITLG/SCF and KIT also transmit signals via GRB2 and activation of RAS, RAF1 and the MAP kinases MAPK1/ERK2 and/or MAPK3/ERK1. KITLG/SCF and KIT promote activation of STAT family members STAT1, STAT3 and STAT5. KITLG/SCF and KIT promote activation of PLCG1, leading to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5- trisphosphate. KITLG/SCF acts synergistically with other cytokines, probably interleukins. Homodimer, non-covalently linked (Probable). Heterotetramer with KIT, binding two KIT molecules; thereby mediates KIT dimerization and subsequent activation by autophosphorylation. Belongs to the SCF family. 3 isoforms of the human protein are produced by alternative splicing. Protein type: Membrane protein, integral. Chromosomal Location of Human Ortholog: 12q22. Cellular Component: extracellular space; cytoskeleton; cytoplasm; integral to membrane; plasma membrane; extracellular region. Molecular Function: protein binding; growth factor activity; cytokine activity; stem cell factor receptor binding. Biological Process: epidermal growth factor receptor signaling pathway; phosphoinositide-mediated signaling; fibroblast growth factor receptor signaling pathway; nerve growth factor receptor signaling pathway; embryonic hemopoiesis; male gonad development; germ cell programmed cell death; signal transduction; positive regulation of MAP kinase activity; cell proliferation; positive regulation of peptidyl-tyrosine phosphorylation; negative regulation of mast cell apoptosis; positive regulation of melanocyte differentiation; innate immune response; positive regulation of myeloid leukocyte differentiation; positive regulation of Ras protein signal transduction; cell adhesion; neural crest cell migration; positive regulation of DNA replication.
