Description：Recombinant Human Interferon lambda-1 Protein is produced by mammalian expression system and the target gene encoding Gly20-Thr200 is expressed with a 6His at the C-terminus.Form：Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.Gene Symbol：IFNL1Alternative Names：IL29; ZCYTO21; Interferon lambda-1; IFN-lambda-1; Cytokine Zcyto21; Interleukin-29; IL-29 Entrez Gene (Human)： 282618; SwissProt (Human)： Q8IU54; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：GPVPTSKPTT TGKGCHIGRF KSLSPQELAS FKKARDALEE SLKLKNWSCS SPVFPGNWDL RLLQVRERPV ALEAELALTL KVLEAAAGPA LEDVLDQPLH TLHHILSQLQ ACIQPQPTAG PRPRGRLHHW LHRLQEAPKK ESAGCLEASV TFNLFRLLTR DLKYVADGNL CLRTSTHPES THHHHHHHHH HDirections 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 ddH2O. 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.
