Product Specs

Introduction
Stem cell factor / KIT ligand (SCF), also known as "steel factor" or "c-kit ligand," is a cytokine that binds to CD117 (c-Kit). It exists in two forms: cell surface bound and soluble (or free), the latter resulting from the cleavage of the former by metalloproteases. SCF is crucial for the survival, proliferation, and differentiation of hematopoietic stem cells and other hematopoietic progenitor cells. Notably, it plays a role in the development of erythrocyte precursors by transforming burst-forming unit-erythroid (BFU-E) cells into colony-forming unit-erythroid (CFU-E) cells.
Description
Recombinant Canine Stem Cell Factor, produced in E. coli, is a single, non-glycosylated polypeptide chain with a molecular weight of 18.4 kDa. It comprises 165 amino acids. The purification process involves proprietary chromatographic techniques.
Physical Appearance
Sterile Filtered White lyophilized powder.
Formulation
The product is lyophilized from a 0.2 µm filtered solution concentrated in PBS with a pH of 7.4.
Solubility
For reconstitution, it is advised to dissolve the lyophilized Stem Cell Factor in sterile 18 MΩ-cm H2O at a concentration not less than 100 µg/ml. This solution can be further diluted into other aqueous solutions as needed.
Stability
Lyophilized SCF, while stable at room temperature for up to 3 weeks, should ideally be stored desiccated at a temperature below -18°C. Once reconstituted, SCF should be stored at 4°C for a period of 2-7 days. For long-term storage, freezing at -18°C is recommended, and the addition of a carrier protein (0.1% HSA or BSA) is advised. Avoid repeated freeze-thaw cycles.
Purity
The purity of the product is determined to be greater than 97.0% using HPLC and SDS-PAGE analysis.
Biological Activity
The biological activity is determined by the dose-dependent stimulation of human TF-1 cell proliferation. The ED50 is less than 2.0 ng/ml, which corresponds to a specific activity of 5,000,000 IU/mg. This indicates full biological activity compared to the standard.
Synonyms
Kit ligand Precursor, C-kit ligand, SCF, Mast cell growth factor, MGF, SF, KL-1, Kitl, DKFZp686F2250.

Product Science Overview

Biological Significance

SCF is essential for the survival, proliferation, and differentiation of hematopoietic stem cells, which are the precursors to all blood cell types. It also supports the migration and proliferation of mesenchymal stem cells (MSCs), which can differentiate into various cell types such as bone, cartilage, and fat cells . This makes SCF a vital component in regenerative medicine and cellular therapies.

Production and Purification

The recombinant canine SCF is produced in E. coli and purified using proprietary chromatographic techniques to ensure high purity and activity . The protein is typically lyophilized from a filtered solution in phosphate-buffered saline (PBS) and can be reconstituted in sterile PBS for use in various applications .

Applications in Research and Medicine

Recombinant canine SCF is widely used in research to study stem cell biology, hematopoiesis, and tissue regeneration. It is also employed in preclinical and clinical settings to enhance the efficacy of stem cell therapies. For instance, SCF has been shown to support the migration and proliferation of canine mesenchymal stem cells, making it a valuable tool in veterinary regenerative medicine .

Storage and Stability

The stability and storage conditions for recombinant canine SCF are critical to maintaining its activity. The lyophilized protein should be stored at -20 to -70°C and reconstituted in sterile conditions to prevent contamination. Once reconstituted, the protein can be stored at 2 to 8°C for up to one month or at -20 to -70°C for up to three months under sterile conditions .
