Recombinant Human IL2 Protein

Description：Recombinant Human IL2 Protein is produced by E. coli expression system and the target gene encoding Ala21-Thr153 is expressed.Form：Lyophilized from a 0.2 μM filtered solution of 10mM sodium citrate, pH 4.0Gene Symbol：IL2Alternative Names：Interleukin-2; IL-2; T-cell growth factor; TCGF; Aldesleukin Entrez Gene (Human)： 3558; SwissProt (Human)： P60568; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：MAPTSSSTKK TQLQLEHLLL DLQMILNGIN NYKNPKLTRM LTFKFYMPKK ATELKHLQCL EEELKPLEEV LNLAQSKNFH LRPRDLISNI NVIVLELKGS ETTFMCEYAD ETATIVEFLN RWITFCQSII STLTDirections 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.
