Description

Our bioactive Stem Cell Factor (SCF) Canine, E. coli Recombinant Protein is a single, non-glycosylated polypeptide chain containing 165 amino acids and has a molecular mass of 18.4 kDa. The SCF is purified by proprietary chromatographic techniques.

Summary

Stem cell factor (SCF), also known as KIT ligand, binds to the receptor-type protein-tyrosine kinase KIT (CD117). This pleiotropic cytokine 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. SCF exists in both a soluble and a transmembrane isoform. SCF is commonly used in cell cultures in vitro to promote expansion of primitive hematopoietic stem cells and multi-potent progenitor cells.

Other Names

Canine SCF, Dog SCF, Canine KIT ligand, c-Kit ligand, KITLG, KL, KL-1, KITL, mast cell growth factor, MGF, Steel factor, SF

Source

E. coli

Formulation

Sterile filtered white lyophilized (freeze-dried) powder. Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4.

Purity

Greater than 97.0% as determined by HPLC and SDS-PAGE.

Biological Activity

Fully biologically active when compared to standard. The ED50 as calculated by the dose-dependent stimulation of the proliferation of human TF-1 cells is less than 2.0 ng/ml, corresponding to a specific activity of 5,000,000 IU/mg.

    Reconstitution

    It is recommended to reconstitute the lyophilized Stem Cell Factor in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.

    Shipping

    At ambient temperature.  Upon receipt, store the product at the temperature recommended below.

    Storage/Expiration

    Lyophilized SCF, although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution, SCF should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.

    Usage

    This product is intended for Laboratory Research Use Only. This product may not be used as a pharmaceutical or veterinary drug, agricultural product, or food additive.
