Human IL1RA protein

• Catalog Number: orb391952
• Category: Proteins
• Description: Recombinant human IL1RA protein is produced by our E. coli expression system and the target gene encoding Arg26-Glu177 is expressed.
• Tested applications: ELISA, MS, SDS-PAGE, WB
• Reactivity: Human
• Form/Appearance: Lyophilized from a 0.2 μM filtered solution of 50mM Tris-HCl, 200mM NaCl, pH 7.5.
• Purity: Greater than 95% as determined by RP-HPLC and reducing SDS-PAGE.

• Source: E. coli
• Endotoxins: Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.
• Storage: Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
• Buffer/Preservatives: Lyophilized from a 0.2 μM filtered solution of 50mM Tris-HCl, 200mM NaCl, pH 7.5.
• Alternative names: IL1F3; IL1RA; Interleukin-1 receptor antagonist pr
• Note: For research use only
• Application notes: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• Expiration Date: 6 months from date of receipt.
