Description：Recombinant Human IFNA4 Protein is produced by Mammalian expression system and the target gene encoding Cys24-Asp189 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.2.Gene Symbol：IFNA4Alternative Names：IFNA4; Interferon alpha-4; IFN-alpha-4; Interferon alpha-4B; Interferon alpha-76; Interferon alpha-M1; IFNA10; Interferon alpha-10; IFN-alpha-10; Interferon alpha-6L; Interferon alpha-C; LeIF C; IFNA14; Interferon alpha-14; IFN-alpha-14; Interferon alpha-H; LeIF H; Interferon lambda-2-H Entrez Gene (Human)： 3441; SwissProt (Human)： P05014; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：CDLPQTHSLG NRRALILLAQ MGRISHFSCL KDRHDFGFPE EEFDGHQFQK TQAISVLHEM IQQTFNLFST EDSSAAWEQS LLEKFSTELY QQLNDLEACV IQEVGVEETP LMNEDSILAV RKYFQRITLY LTEKKYSPCA WEVVRAEIMR SLSFSTNLQK RLRRKDVDHH HHHH*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.
