Description: Recombinant Human IL11 Protein is produced by P. pastoris by recombinant DNA technology. The protein has a molecular mass of approximately 19000 Daltons and is non-glycosylated. The protein is 177 amino acids in length and differs from the 178 amino acid length of native IL-11 by lacking the amino-terminal praline residue. Form: Lyophilized from a 0.2 μM filtered solution of 20mM PB, 2% Glycine, pH 7.2. Gene Symbol: IL11 Alternative Names: Interleukin-11; IL-11; Adipogenesis inhibitory factor; AGIF; OprelvekinEntrez Gene (Human): 3589SwissProt (Human): P20809Purity : Greater than 95% as determined by RP-HPLC and reducing SDS-PAGE.Chemical Structure : PGPPPGPPRV SPDPRAELDS TVLLTRSLLA DTRQLAAQLR DKFPADGDHN LDSLPTLAMS AGALGALQLP GVLTRLRADL LSYLRHVQWL RRAGGSSLKT LEPELGTLQA RLDRLLRRLQ LLMSRLALPQ PPPDPPAPPL APPSSAWGGI RAAHAILGGL HLTLDWAVRG LLLLKTRL Directions 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.
