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: IFNL1 Alternative Names: IL29; ZCYTO21; Interferon lambda-1; IFN-lambda-1; Cytokine Zcyto21; Interleukin-29; IL-29Entrez Gene (Human): 282618SwissProt (Human): Q8IU54Purity : 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 H 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 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.
