Handling Advice: Always centrifuge tubes before opening. Do not mix by vortex or pipetting.

Storage: 4 °C/-20 °C/-80 °C

Storage Comment: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.

Expiry Date: 6 months

Target Details

Target: FSTL1 (Follistatin-Like 1 (FSTL1))

Alternative Name: Follistatin-Related Protein 1/FSTL1 (FSTL1 Products)

Background: Recombinant Human Follistatin-Related Protein 1/FSTL1 is produced with our E. coli expression system. The target protein is expressed with sequence (Glu21-Ile308) of Human FSTL1 fused with a 6His tag at the C-terminus.
Follistatin-Related Protein 1 (FSTL1) is a secreted protein that contains two EF-hand domains, one follistatin-like domain, one Kazal-like domain, and one VWFC domain. Its functional significance in physiological and pathological processes is not completely understood. However, FSTL1 is thought to modulate the action of some growth factors on cell proliferation and differentiation. FSTL1 maybe an autoantigen associated with rheumatoid arthritis.
