GRADE & PURITYCarrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.PBS Only?PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers.≥95%(SDS-PAGE)See COA

Recombinant Human IFN-alpha-1a Protein (rp222551) - ELISA Immobilized Recombinant Human IFN-alpha-1a Protein (rp222551) at 1.0 μg/mL can bind Rontalizumab (anti-IFNA1) (Ab175647) with the EC₅₀ of 60.2 ng/mL.
Recombinant Human IFN-alpha-1a Protein (rp222551) - SDS-PAGE 3 μg/lane of Recombinant Human IFN-alpha-1a Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 18.3 kDa under reducing conditions and 16.8 & 33.1 kDa under non-reducing conditions. The observation of protein as both dimers and monomers under non-reducing (NR) conditions suggests that a portion of the protein forms dimers. This dimerization may be mediated by (or stabilized by) disulfide bonds (Uniprot: P01562).
