Research Overview
IFN-alpha-2b
Extensively studied recombinant type I interferon with direct antiviral and immunoregulatory effects. Clinical literature spans hepatitis treatment, antiviral research, and immune-oncology contexts.
Glatiramer Acetate
Glatiramer acetate has extensive literature in relapsing-remitting multiple sclerosis, where it is used to shift immune activity away from pro-inflammatory pathways. It remains one of the best-studied peptide-based immunomodulators and a benchmark compound for autoimmunity research.
