Research AreasCell Biology

Function

Binds directly to activin and functions as an activin antagonist. Inhibits activin A signaling in the iris and regulates somatostatin phenotype in ciliary ganglion neurons. Specific inhibitor of the biosynthesis and secretion of pituitary follicle stimulating hormone (FSH).

Biological Context

Subcellular Location: Secreted
Tissue Specificity: Ciliary ganglion neurons. Levels are higher in the iris than the choroid

Product Specifications

Recombinant Chicken Follistatin (FST) is a recombinant protein from Gallus gallus (Chicken), expressed in E.coli, covering amino acids 29-343aa, with C-terminal 6xHis-tagged tag, molecular weight 41.8kDa, purity Greater than 85% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.

Western Blot: Compatible with standard Western Blot protocols.
