• Cat.No.: IFNA-358C
• Product Overview: Recombinant Cynomolgus IFNA protein(EHH53981.1)(27-243 aa), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Cynomolgus
• Source: HEK293
• Tag: His
• Protein Length: 27-243 aa
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Cynomolgus IFN alpha/beta R2, His Tag captured on CM5 Chip via anti-his antibody can bind Human IFN alpha 1, hFc Tag with an affinity constant of 70.28 nM as determined in SPR assay (Biacore T200).
• Molecular Mass: The protein has a predicted MW of 25.93 kDa. Due to glycosylation, the protein migrates to 43-60 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
• Storage: -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
