Description
Recombinant Human Interleukin-1 Receptor Antagonist Protein is produced by our E.coli expression system and the target gene encoding Arg26-Glu177 is expressed.
Alias
Interleukin-1 Receptor Antagonist Protein; IL-1RN; IL-1ra; IRAP; ICIL-1RA; IL1 Inhibitor; Anakinra; IL1RN; IL1F3; IL1RA
Endotoxin Testing
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Activity
Measured by the dose-dependent inhibition of IL-1 stimulation of D10S cells.The ED50 for this effect is typically 0.5 ng/mL.
Formulation
Lyophilized from a 0.2 μm filtered solution of 50mM TrisHCl, 200mM NaCl, pH 7.5.
Storage
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.
Warranty
For Research Use Only. Our recombinant proteins can not be used in diagnostic procedures.
