Cat. No.	Z102505
Name	Recombinant Human Maspin (SerpinB5) (E. coli)
Description	Mammary serine protease inhibitor (Maspin) is a non-inhibitory tumor suppressor serpin that is encoded by the SERPINB5 gene. Playing an important role in embryonic development in cell adhesion, Maspin has the ability to suppress the growth, invasion, and metastasis of breast and lung tumors. However, Maspin does not exhibit any serine protease inhibitor activity since it does not undergo the conformational transition from stressed to relaxed found in typical serpins. It is expressed in normal breast and prostatic epithelial cells, but downregulated in most breast carcinoma.
Organism	Human (H. sapiens)
Unit quantity	20 µg
Family	Somatotropin/Sclerostin/Serpin Families
Aliases	PI5, maspin
Gene Symbol	SERPINB5
Gene ID	5268
Accession Number	P36952
Source	E. coli
Species	Human (H. sapiens)
Appearance	Lyophilized Powder
Molecular Weight	42.3 kDa
Endotoxin Level	<1.0 EU/µg of recombinant protein as determined by the LAL method
Purity	>95% as determined by SDS-PAGE
Function	The ED(50) was determined by the dose-dependent proliferation of MDA-MB-468 cells and was found to be <0.05ng/mL.
Storage	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.
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. Z102505

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.
