This protein is produced using HEK293 cells, ensuring optimal purity and activity. With its His Tag, it is easily detectable and purifiable, making it a valuable addition to your laboratory.

Key Features and Specifications

Our Follistatin/FST (FS288) Protein is a recombinant protein derived from human FST gene, with a sequence spanning Met 1-Asn 317. It has a calculated molecular weight of 33 kDa and an observed molecular weight of 45 kDa. This protein is highly pure, exceeding 90% purity as determined by reducing SDS-PAGE. It is also free from endotoxins, with less than 1.0 EU per μg as determined by the LAL method. This product is lyophilized from sterile PBS, pH 7.4, and contains 5% - 8% trehalose, mannitol, and 0.01% Tween 80 as protectants.

Applications and Benefits

This recombinant Follistatin/FST (FS288) Protein is a potent activin antagonist, specifically inhibiting follicle-stimulating hormone release and playing a crucial role in the activin-follistatin system. It has been shown to neutralize Activin-mediated inhibition on MPC11 cell proliferation, with an ED50 typically ranging from 0.2-1 μg/mL in the presence of 10 ng/ml Recombinant Human Activin A. This protein is ideal for various applications, including cell culture, ELISA, and other in vitro assays. With its proven bio-activity and high purity, it is a reliable choice for researchers seeking to study the complex interactions of the activin-follistatin system.
