Description：Recombinant Human IL-28A Protein is produced by mammalian expression system and the target gene encoding Val26-Val200 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.Gene Symbol：IFNL2Alternative Names：IL28A; ZCYTO20; Interferon lambda-2; IFN-lambda-2; Cytokine Zcyto20; Interleukin-28A; IL-28A Entrez Gene (Human)： 282616; SwissProt (Human)： Q8IZJ0; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：VPVARLHGAL PDARGCHIAQ FKSLSPQELQ AFKRAKDALE ESLLLKDCRC HSRLFPRTWD LRQLQVRERP MALEAELALT LKVLEATADT DPALVDVLDQ PLHTLHHILS QFRACIQPQP TAGPRTRGRL HHWLYRLQEA PKKESPGCLE ASVTFNLFRL LTRDLNCVAS GDLCVHHHHH 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.
