Neutralizing Antibodies | Functional Blocking Antibodies

Browse 700+ neutralizing antibodies with verified blocking and inhibitory activity. Designed for functional studies including cytokine neutralization, receptor-ligand blocking, viral infectivity inhibition, and pathway modulation in cell-based assays. Each antibody is validated with IC₅₀/ND₅₀ data or functional blocking assay results. All products are designated Research Use Only (RUO) — not intended for diagnostic or therapeutic procedures. RUO

Why Researchers Choose abinScience

Verified Neutralizing Activity Every antibody is functionally validated — IC₅₀ or ND₅₀ determined by cell-based neutralization, receptor-binding inhibition, or bioactivity blocking assay.

Cytokine & Receptor Blocking Neutralize TNF-α, IL-6, IL-1β, IFN-γ, and other inflammatory mediators. Block receptor-ligand interactions (PD-1/PD-L1, CTLA-4/CD80, VEGF/VEGFR) for pathway studies.

In Vivo Compatible Many neutralizing antibodies are available in low-endotoxin, azide-free formulations suitable for in vivo administration in preclinical animal models.
