Recombinant equine interleukin-1 receptor antagonist (IL-1RN/IL-1RA) expressed in E. coli and supplied as a lyophilized, N-terminal 6xHis-tagged protein. It is intended for research into IL-1 signaling and inflammatory processes, and is provided with formulation, purity, and storage information to support experimental use.
- Expressed in E. coli with an N-terminal 6xHis tag.
- Derived from equine (horse) sequence (UniProt O18999, residues H26-Q177).
- Predicted mass 17.2 kDa; observed ~18 kDa by SDS-PAGE.
- Purity greater than 95% as determined by reducing SDS-PAGE.
- Lyophilized from 50 mM Tris-HCl, 300 mM NaCl, pH 7.4.
- Store lyophilized at -20°C; after reconstitution, aliquot and store at -20°C or -80°C for long term.
- Available in multiple sizes including 50 μg and 100 μg.
