分子别名(Synonym):IFB,IFF,IFN-beta,IFNB,Interferon beta

种属(Species):Human

表达系统(Expressed Host):CHO Stable Cells

产品状态(Buffer):Lyophilized from sterile 10mM NaAC, 40mM Arg, 0.12mg/ml Met, 146mg/ml Sucrose, 0.1% PF-68, pH 4.5

分子量(Molecule Mass):The recombinant human IFNβ consists of 166 amino acids and predicts a molecular mass of 20 KDa. It migrates as an approximately 20-23 KDa band in SDS-PAGE under reducing conditions.

内毒素(Endotoxin):<1.0 EU per μg by the LAL method.

生物活性(Activity):Measured in antiviral assays using WISH cells infected with vesicular stomatitis virus. The ED50 for this effect is typically 2-20 pg/mL.

表达区间(Protein Construction):A DNA sequence encoding the human IFNβ (P01574) (Ser2-Asn187) was expressed.

存储条件(Storage): For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件: In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

使用及储存:

Store it under sterile conditions at -20℃ to -80℃ upon receiving. Recommend to aliquot the protein into smaller quanti࿒࿒5516}ā
