−Key Properties
−| Source | E.coli |
|---|---|
| Target | FSTL1 |
| Reactivity | Human |
| Tag | C-6×His Tag |
| MW | The protein has a predicted molecular mass of 33.5 kDa after removal of the signal peptide. The apparent molecular mass of FSTL1-His is approximately 35-55 kDa due to glycosylation. |
| Purity | The purity of the protein is greater than 85% as determined by SDS-PAGE and Coomassie blue staining. |
Storage & Handling
−| Storage | Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature. |
|---|---|
| Form/Appearance | Lyophilized from a 0.2 μm filtered solution of 20mM Tris-HCl,500mM NaCl,5%Trehalose,5%Mannitol,0.01%tween80,1mM EDTA,pH8.0. |
