Product Specifications

Abbreviation

FST

Synonyms

Host

HEK 293

Tag

C-His

Endotoxin

< 1.0 EU per μg of the protein as determined by the LAL method

Purity

> 90 % as determined by SDS-PAGE

Bioactivity

Measured by its ability to neutralize Activin-mediated inhibition on MPC11 cell proliferation. The ED50 for this effect is typically 20-80 ng/mL in the presence of 10 ng/mL Recombinant Human Activin A.

Function

Met1-Asn317

Molecular Weight

The secreted recombinant human FST (FS288) consists of 299 amino acids and has a predicted molecular mass of 33 kDa. As a result of glycosylation, rhFST (FS288) migrates as an approximately 45 kDa band in SDS-PAGE under reducing conditions.
