Our Latest Coronavirus Antibodies

The Native Antigen Company offers an extended range of coronavirus antibodies, including SARS-CoV-2 Nucleoprotein monoclonals and matched pairs, SARS-CoV-2 monoclonal nanobodies, and polyclonals against the four HCoV NPs. For more information on these products, click the buttons below:

New SARS-CoV-2 Nucleoprotein Monoclonals

Our latest matched-pair Nucleoprotein capture and detection antibodies are ideal for the development of highly specific SARS-CoV-2 immunoassays. Tested in sandwich ELISA, these antibodies show high affinity for SARS-CoV-2 Nucleoprotein.

MAB12468-MAB12465 Matched Pair

Binding data of MAB12468 (capture antibody) in sandwich ELISA.

SARS-CoV-2 Nucleoprotein Capture-Detection Assay

Sandwich ELISA format for our NP matched-pairs.

New SARS-CoV-2 Spike Nanobodies

The Native Antigen Company now offers VHH nanobodies, comprising the heavy chain Fab fragments of llama anti-SARS-CoV-2 Spike antibodies. These antibodies show differential neutralising activity against wild-type SARS-CoV-2 and its variants, and are suitable for use in the development of ELISAs and neutralisation assays.

MAB12474 Neutralisation Assay

Inhibitory activity of nanobody (MAB12474) against SARS-CoV-2 RBD binding to ACE2, as determined by ELISA.

New HCoV Spike Polyclonals

The Native Antigen Company now offers anti-HCoV S1 polyclonals. These antibodies have shown to not bind SARS-CoV-2 S1 in ELISA, making them suitable for the development of non-SARS-CoV-2 coronavirus assays, including ELISAs and Western blots.


PAB21478 antigen-down ELISA with HCoV-229E (REC31895), HCoV-HKU1 (REC31897), HCoV-OC43 (REC31894), HCoV-NL63 (REC31896), SARS-CoV (REC31809) and SARS-CoV-2 (REC31806) Spike subunit 1 proteins.

The Role of Serology in Tracking COVID-19 Mutations

This article was originally published on Clinical Lab Products. As SARS-CoV-2 began its global proliferation in early 2020, scientists hastened to investigate its biology, develop diagnostic tests, and design candidate vaccines, marking one of the most...

Preparing for Disease Y: A Better Serological Toolbox

This article was originally published on Clinical Lab Manager. It’s been over a year since the World Health Organization (WHO) declared COVID-19 a pandemic. SARS-CoV-2 has since infected 200 million people, resulting in nearly 4 million deaths and substantial economic...

Keeping Up with the New SARS-CoV-2 Variant Nomenclature

If you’ve been struggling to make sense of SARS-CoV-2 variant nomenclature, you’re not alone. Due to the existence of multiple genomic sequence databases, various naming systems are in use for the rapidly growing range of SARS-CoV-2 variants of concern/interest. In a...

Making Sense of the SARS-CoV-2 Spike Mutations

Through much of 2020, SARS-CoV-2 accumulated mutations at a steady, yet unspectacular rate. However, as global cases approached 100 million by the end of the year, multiple variants began to emerge. Exhibiting more considerable genomic changes, some variants have...

D614G: Putting the Mutation in Perspective

Since the emergence of SARS-CoV-2, scientists have speculated about the risks of mutation and what this could mean for therapeutics and vaccines. In this blog, we explore the nature viral mutation, what is known about the D614G mutant of SARS-CoV-2, and introduce our...

The Endemic Coronaviruses and What They Might Tell us About COVID-19

While less-well known than some of their counterparts, the 229E, NL63, OC43, and HKU1 human coronaviruses are a significant cause of respiratory disease worldwide. The evolutionary histories and host associations of the endemic coronaviruses also provide important...

Q&A: An Insight Into COVID-19 Serology

During the course of the current coronavirus pandemic, we have all been aware of the urgent need for nucleic acid testing to identify people currently infected with SARS-CoV-2. The second form of testing needed are serological immunoassays, which can identify past...

A Q&A with David Flavell of Leukaemia Busters

In this blog, we speak with Dr. David Flavell about his scientific career, the legacy of Leukaemia Busters, and the recent impact that COVID-19 has had on his research.Tell me about your scientific background David. I was born in a seaside town called Southport in the...

Avoiding the Immunopathology Pitfalls of a COVID-19 Vaccine
