Introduction

FSTL1 protein resembles follistatin, an activin-binding protein. FSTL1 is an autoantigen associated with rheumatoid arthritis and it holds an FS section, a follistatin-like sequence having 10 conserved cysteine residues.

Description

FSTL1 Human Recombinant produced in HEK293 cells is a single, glycosylated polypeptide chain (a.a 21-308) containing 296 amino acids including a 8 a.a C-terminal His tag. The total molecular mass is 33.8kDa (calculated). 

Source

HEK293 cells.

Physical Appearance

Filtered White lyophilized (freeze-dried) powder.

Formulation

FSTL1 filtered (0.4 µm) and lyophilized from 0.5mg/ml in phosphate buffered saline and 5 % (w/v) trehalose, pH 7.4. 

Solubility

It is recommended to add 200µl deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. FSTL1 is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.

Stability

Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after one week at 4°C.

Purity

Greater than 95.0% as determined by SDS-PAGE.
