Human Follistatin-like 1 / FSTL1 Protein, His Tag

分子别名(Synonym)

FSTL1,FRP,FSL1

表达区间及表达系统(Source)

Human Follistatin-like 1, His Tag (FS1-H5227) is expressed from human 293 cells (HEK293). It contains AA Glu 21 - Ile 308 (Accession # AAH00055).

Predicted N-terminus: Glu 21

蛋白结构(Molecular Characterization)

Online(Glu 21  - Ile 308) AAH00055

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 33.8 kDa. The protein migrates as 35-50 kDa under reducing (R) condition (SDS-PAGE) due to differtent glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景(Background)

Follistatin-related protein 1 (FSTL1) is also known as Follistatin-like protein 1 (FRP). FSTL1 is a secreted protein that contains two EF-hand domains, one follistatin-like domain, one Kazal-like domain and one VWFC domain. FSTL1 is overexpressed in synovial tissues from rheumatoid arthritis. Follistatin-like protein 1 / FSTL1 may modulate the action of some growth factors on cell proliferation and differentiation. FSTL1 binds heparin.
