The NCF2 Antibody, HRP (Horseradish Peroxidase) Conjugated, is a specialized immunoassay reagent designed to detect Neutrophil Cytosolic Factor 2 (NCF2), a 67 kDa protein encoded by the NCF2 gene. NCF2, also known as p67phox, is a critical cytosolic subunit of the NADPH oxidase complex responsible for reactive oxygen species (ROS) production in phagocytic cells . The HRP conjugation enables enzymatic signal amplification in applications like ELISA, facilitating direct detection of NCF2 without requiring secondary antibodies .
ELISA: Direct quantification of NCF2 in human samples using chemiluminescent or colorimetric substrates .
Western Blot (WB): Detection of endogenous NCF2 at ~60–67 kDa in cell lysates .
Immunohistochemistry (IHC): Localization of NCF2 in paraffin-embedded tissues (e.g., human tonsil, mouse spleen) .
ROS Regulation: NCF2/p67phox is essential for NADPH oxidase activity. Knockdown of NCF2 via siRNA reduces intracellular ROS by 80%, leading to apoptosis in HCT116 and HaCat cells .
Chronic Granulomatous Disease (CGD): Mutations in NCF2 impair phagocytic ROS production, increasing susceptibility to infections .
Substrates: Pair with chemiluminescent (e.g., SuperSignal™) or chromogenic (e.g., TMB) substrates for ELISA .
Signal Amplification: Use tyramide-based kits (e.g., Invitrogen SuperBoost) for low-abundance targets .
Protocol Optimization: Antigen retrieval with EDTA buffer (pH 8.0) recommended for IHC .
