Description

Description générale

Stem Cell Factor (SCF), also known as c-Kit ligand (KL), steel factor (SLF) and mast cell growth factor (MGF), is a 30 kDa glycoprotein with broad activities on various tissues, including hematopoietic cells, pigment cells, and primordial germ cells. SCF is secreted by endothelial cells, fibroblasts, and bone marrow stromal cells as a membrane-bound form which may be cleaved to release the soluble form. Both forms are active in promoting colony formation from murine bone marrow cells, but membrane-bound SCF is more effective in promoting hematopoieses in vivo, suggesting a role in cellular interactions between hematopoietic and stromal cells. The soluble form is thought to exist in solution as a noncovalently linked dimer. SCF is structurally related to M-CSF (CSF-1) and Flt-3/Flk-2 Ligand (FL) with all three sharing a similar size, existence of transmembrane and soluble forms, four conserved cysteines, and alternative splicing exon locations, but they share little sequence homology. SCF alone is a modest colony stimulating factor. However, in the presence of other cytokines such as EPO, TPO, GM-CSF, G-CSF, M-CSF, IL-3, and IL-7, SCF is a potent costimulant that works synergistically to increase the size of myeloid, erythroid or lymphoid lineage colonies without influencing the lineage differentiation of the progenitors.

Spécificité

Reacts with mouse SCF; SCF is highly conserved cross reactivity with rat, human and other species SCF is expected but untested.

Immunogène

Highly pure (>98%) recombinant mouse SCF

Application

Detect Stem Cell Factor using this Anti-Stem Cell Factor Antibody validated for use in ELISA, WB, NEUT.

ELISA: To detect mSCF by direct ELISA (using 100 μL/well antibody solution) a concentration of at lease 0.5 μg/mL of this antibody is required. Should allow detection of 0.2 - 0.4 ng/well of recombinant mSCF.

Neutralization: For ½ maximal inhibition (ND50) of the bioogical activity of mSCF (20 ng/mL), a concentration of 0.64 - 0.97 μg/mL is required.

Western blot: 0.1 - 0.2 μg/mL, this dilution should offer a detection limit of 1.5-3.0 ng/lane, under either reducing or non-reducing conditions.

Optimal working dilutions must be determined by the end user.
