Cat. No.	Z101035
Name	Recombinant Human Follistatin (FST)
Description	Expressed in the pituitary, ovaries, and in some other tissues, FST is a high affinity activin binding protein that can act as an activin antagonist. FST was originally discovered through its suppressive effect of the expression and secretion of the pituitary follicle stimulating hormone. Besides activin, FS has also been shown to bind with multiple BMPs, Myostatin, GDF-11, and TGF-beta-1. Human Follistatin contains three cysteine-rich domains (called Follistatin-like domains), 3 Kazal-like domains and one TGF-beta binding domain.
Organism	Human (H. sapiens)
Unit quantity	10 µg
Family	Other Growth Factors/Cytokines
Tag	Tag Free
Aliases	FS
Gene Symbol	FST
Gene ID	10468
Accession Number	P19883
Source	E. coli
Species	Human (H. sapiens)
Appearance	Lyophilized Powder
Molecular Weight	31 kDa
Endotoxin Level	<1.0 EU/µg of recombinant protein as determined by the LAL method.
Purity	>95% as determined by SDS-PAGE
Formulation	Recombinant Human Follistatin was lyophilized at 1.0 mg/mL containing no additives.
Function	The ED(50) was determined by the ability to neutralize Activin A inhibitory effect of mouse MPC-11 cells and was determined to be 0.1-0.4 µg/mL in the presence of 7.5 ng/mL Activin A.
Reconstitution	A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Shipping Conditions	This lyophilized protein is shipped at ambient temperature. Cold packs may be used if transit temperatures are elevated. The product remains stable during normal shipping conditions.
Storage	Upon receipt, store lyophilized protein at –70°C for long-term storage. Short-term storage at –20°C is acceptable if necessary. Once reconstituted, store at 2–8°C for up to 1 month, or at –20°C for up to 6 months. Avoid repeated freeze/thaw cycles.
Usage	For research use only. Not for diagnostic or therapeutic use.
Material Citation	If use of this material results in a scientific publication, please cite the material in the following manner: Applied Biological Materials Inc, Cat. No. Z101035

How do I choose the right growth factor for my experiment?

Cell type: Different cells respond to different growth factors. Choose a growth factor that promotes the growth or differentiation of your target cell type.
Desired outcome: Whether you are studying proliferation, differentiation, or survival, different growth factors will promote different cellular behaviors.
Concentration and formulation: Different experiments may require varying concentrations of growth factors.

	What is the shelf life and storage condition of this product?
	The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
