Description：Recombinant Mouse IL4 Protein is produced by E. coli expression system and the target gene encoding His23-Ser140 is expressed.Form：Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4.Gene Symbol：IL4Alternative Names：Interleukin-4; IL-4; B-cell stimulatory factor 1; BSF-1; Binetrakin; Lymphocyte stimulatory factor 1; Pitrakinra Entrez Gene (Mouse)： 16189; SwissProt (Mouse)： P07750; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MHGCDKNHLR EIIGILNEVT GEGTPCTEMD VPNVLTATKN TTESELVCRA SKVLRIFYLK HGKTPCLKKN SSVLMELQRL FRAFRCLDSS ISCTMNESKS TSLKDFLESL KSIMQMDYSDirections 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.
