SARS-CoV-2 is structurally composed of 4 main proteins (e.g. spike glycoprotein, envelope glycoprotein, membrane glycoprotein and nucleocapsid protein) and several accessory proteins.  The SARS-CoV-2 Nucleocapsid (N) is an abundant protein, that binds to the viral RNA and helps stabilize it. It has been proposed that N protein forms bimolecular condensates that both regulate viral replication and modulate the host response to the virus following infection.  N protein is a major antigen that the host immune response is directed to following SARS CoV-2 infection making it a promising candidate for vaccine development and drug therapy.\u003cbr\u003e\n25μg\u003cbr\u003e\nVerified Reactivity: SARS-CoV-2\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: SARS-CoV-2 Nucleocapsid recombinant protein\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography.\u003cbr\u003e\nConcentration: 0.5 mg\/mL\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C.\u003cbr\u003e\nApplication: WB - Quality tested Direct ELISA, ICFC - Verified\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.125 - 1.0 µg\/mL. For Direct ELISA application, a concentration of 3.7 ng\/mL is recommended. For intracellular flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.\u003cbr\u003e\nApplication Notes: SARS-CoV-2 is 90% homologous to SARS-CoV. Cross reactivity of anti-SARS-CoV-2 Nucleocapsid antibody (clone A20087H) with SARS-CoV has not been tested. BioLegend offers two clones specific for SARS-CoV-2 nucleocapsid, clones A20087F and A20087H Both clones have been verified for western blot, with A20087F showing a higher affinity for SARS-CoV-2 nucleocapsid for this application Both clones have been verified for direct ELISA and displayed similar EC50 values for this application A20087H has been verified for ICFC, while A20087F is not recommended for this application\u003cbr\u003e\nRRID: AB_2892515 (BioLegend Cat.
