Description：Recombinant Human IL1RN Protein is produced by E. coli expression system and the target gene encoding Arg26-Glu177 is expressed.Form：Lyophilized from a 0.2 μM filtered solution of 50mM Tris-HCl, 200mM NaCl, pH 7.5.Gene Symbol：IL1RNAlternative Names：IL1F3; IL1RA; Interleukin-1 receptor antagonist protein; IL-1RN; IL-1ra; IRAP; ICIL-1RA; IL1 inhibitor; Anakinra Entrez Gene (Human)： 3557; SwissProt (Human)： P18510; Purity：Greater than 95% as determined by RP-HPLC and reducing SDS-PAGE.Chemical Structure：MRPSGRKSSK MQAFRIWDVN QKTFYLRNNQ LVAGYLQGPN VNLEEKIDVV PIEPHALFLG IHGGKMCLSC VKSGDETRLQ LEAVNITDLS ENRKQDKRFA FIRSDSGPTT SFESAACPGW FLCTAMEADQ PVSLTNMPDE GVMVTKFYFQ EDEDirections for Use：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.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability：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.
