描述

Cell Therapy Systems CTS™ Recombinant Human Stem Cell Factor (SCF) is a bioactive protein intended for use in cell culture applications, including pre-clinical and clinical cell therapy studies. SCF is a pleiotropic factor that acts in utero in germ cell and neural cell development and hematopoiesis. These activities are all believed to reflect a role in cell migration. In adults, it functions pleiotropically, while mostly noted for its continued requirement in hematopoiesis. The lyophilized, E. coli-expressed SCF CTS™ Recombinant Human is verified for activity through dose-dependent proliferation of human MO-7e cells.

• Qualified—helps reduce your burden in qualifying reagents for regulatory submission in cell therapy applications
• Highly Pure—minimizes interference from other proteins or contaminants
• Active—get more results with less protein

Simplified Transition into Clinical Research
GIBCO® CTS™ products are of high quality and supplied with harmonized documentation such as Certificates of Analysis, Certificates of Origin, and access to authorization letters for our Drug Master Files, as appropriate. The GIBCO® CTS™ product line enables you to reduce your burden in qualifying reagents during your transition from research applications to clinical applications.

High Purity
To help verify that GIBCO® CTS™ Recombinant growth factors are of the highest quality, each protein is analyzed for purity, along with structural homogeneity, to help ensure a biologically active protein. The purity of each GIBCO® CTS™ recombinant growth factor is verified by SDS-PAGE to be over 95% and to have endotoxin levels below 0.1 ng/μg.

High Biological Activity
All GIBCO® CTS™ Recombinant growth factors are verified for activity. Each lot has its own ED50 determined using an activity assay based on a specific function of the growth factor. The activity of our SCF CTS™ Recombinant Human growth factor is determined by the dose-dependent proliferation of human MO-7e cells to have an ED50 range of 2–10 ng/mL (specific activity: 5 × 10⁵–1 × 10⁵ units/mg). Optimal concentration for individual applications should be determined by a dose response assay.
