Natural and recombinant human Follistatin.

Cross-reactivity

< 0.5% cross-reactivity observed with available related molecules.< 50% cross-species reactivity observed with species tested.

Interference

Interference observed with 1 or more available related molecules.

*The Sample Volume represented is based on the amount of sample incorporated into the reaction after taking into account the assay’s minimum required dilution for a given matrix. Serial dilution may be necessary to achieve some of the final sample volumes represented.

Product Summary

Simple Plex assay for the detection of human Follistatin in cell culture supernatant (CCS), serum, and EDTA plasma.

Recovery

Recovery was not necessary as Follistatin shows natural linearity data from a neat sample to a 1:16 dilution.

Linearity

Samples containing and/or spiked with high concentrations of human Follistatin were serially diluted with Sample Diluent to produce samples within the dynamic range of the assay

Background: Follistatin

Follistatin (FST) is a secreted glycoprotein that binds and neutralizes several TGF-beta superfamily proteins including Activin, BMP-6, BMP-7, and GDF-8/Myostatin. It also binds Angiogenin and regulates hematopoietic stem cell adhesion to Fibronectin. Some Follistatin binding partners will also bind Follistatin-like proteins such as FSL-3. Of three follistatin isoforms, the full-length mature follistatin (FST315) is the most abundant and the sole form in plasma, but has lower binding affinity for both activins and heparins than alternative forms. The acidic tail is missing in the splice variant FST288, which shows highest affinity, and partial in the proteolytically produced FST303, which shows intermediate affinity. Genetic deletion of follistatin in mice, or expression of only the FST288 form, is lethal perinatally due to defects of lung, skin and musculoskeletal system. Expression of only the FST315 isoform allows survival, with defects in vascularization and female fertility.
