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: IL4 Alternative Names: Interleukin-4; IL-4; B-cell stimulatory factor 1; BSF-1; Binetrakin; Lymphocyte stimulatory factor 1; PitrakinraEntrez Gene (Mouse) : 16189SwissProt (Mouse) : P07750Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : MHGCDKNHLR EIIGILNEVT GEGTPCTEMD VPNVLTATKN TTESELVCRA SKVLRIFYLK HGKTPCLKKN SSVLMELQRL FRAFRCLDSS ISCTMNESKS TSLKDFLESL KSIMQMDYS 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.
