Rabbit polyclonal antibody against the SARS-CoV-2 nucleocapsid (N) protein, affinity-purified, 0.1 mg (larger quantities available on request). Raised and purified against the recombinant SARS-CoV-2 nucleocapsid protein. Supplied lyophilised and preservative-free, making it directly suitable for conjugation to gold, latex or enzyme labels — the intended reagent for SARS-CoV-2 antigen ELISA and lateral-flow rapid-test development.

APPLICATIONS
- ELISA — SARS-CoV-2 nucleocapsid antigen immunoassay (capture or detection arm).
- Lateral flow rapid test — antigen-detection strip development; preservative-free format allows direct conjugation to colloidal gold or latex.
APPLICATION HIGHLIGHTS — HIGH-VALUE RESEARCH NICHES
- Rapid antigen test development — nucleocapsid is the most abundant SARS-CoV-2 protein and the standard lateral-flow target.
- Point-of-care diagnostics — preservative-free antibody suitable for gold and latex conjugation without prior dialysis.
- Viral load and shedding studies — N-protein quantification in clinical and environmental samples.
- Wastewater and surveillance epidemiology — antigen-based SARS-CoV-2 monitoring.
- Coronavirus biology — nucleocapsid function in viral RNA packaging and assembly.
