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.
纯度
> 95 % as determined by reducing SDS-PAGE.
过滤
0.2 μm filtered
内毒素水平
Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
缓冲液
Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
注意事项
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
储存条件
4 °C/-20 °C/-80 °C
储存方法
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.
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.
