GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.≥95%(SDS-PAGE)See COA

Biochemical and Physiological Mechanisms
Interferon-alpha (IFN-alpha), also known as leukocyte interferon, represents a group of related but distinct proteins that share over 95% amino acid sequence homology. They are members of the type I interferon family which share a common cell surface rece
21.0- 28.4 kDa, under reducing conditions; 17.0-25.4 kDa, under non-reducing conditions.

Recombinant Human IFN-alpha H2/IFN-α14 Protein (rp222560) - SDS-PAGE
3 μg/lane of Recombinant Human IFN-alpha H2/IFN-α14 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 21.0-28.4 kDa under reducing conditions and 17.0-25.4 kDa non-reducing conditions.
The presence of two bands under non-reducing conditions may be due to the protein existing in two diferent conformations in this state (Uniprot: P01570).
