Ms Recom SCF, 500 µg

STEMCELL Technologies supplies a Mouse Recombinant SCF preparation expressed in E. coli, presented as a solid and intended for use as a laboratory reagent. According to the manufacturer's product page, SCF is described as an early-acting cytokine that plays a pivotal role in the regulation of embryonic and adult hematopoiesis.

The biological activity of the recombinant protein was tested by its ability to promote the proliferation of TF-1 cells, with proliferation measured after 65 hours of culture using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum, and in the cited example was 5.7 - 8.6 ng/mL. SDS-PAGE analysis under reducing and non-reducing conditions, visualized by Coomassie Blue staining, indicates a predicted molecular mass of 18.4 kDa.

The Safety Data Sheet (document DX22121) classifies the product as not a hazardous substance or mixture according to the Globally Harmonized System (GHS). The manufacturer and supplier is STEMCELL Technologies Canada Inc., based at Suite 500 - 1618 Station Street, Vancouver, British Columbia V6A 1B6, Canada, with an emergency telephone number of 1-800-667-0322.
