SARS-CoV-2 Products – Antibodies, Assays, & Recombinant Proteins
Active Motif’s Unique Offering of Reagents for SARS-CoV-2
COVID-19 is one of the biggest public health issues in history and presents a unique challenge to the scientific research community – to develop reagents, diagnostics, and therapeutics more quickly than has ever been done.
Active Motif was one of the first companies to be involved in a key collaboration that led to the first cloning, expression, and characterization of recombinant human antibodies from patients who were infected with SARS-CoV-2, mounted an immune response, and recovered. Many of these recombinant antibodies are now available for commercial and research purposes. We also offer multiple recombinant SARS-CoV-2 proteins, including various formats of the SARS-CoV-2 Spike S1 protein, as well as many of the SARS-CoV-2 nonstructural proteins. We have additionally utilized these recombinant antibodies and proteins to create a SARS-CoV-2 Spike S1 protein ELISA.
Recombinant SARS-CoV-2 Antibodies
In partnership with our collaborators at Fudan University, Active Motif scientists successfully performed single-cell analysis of B cells from patients who recovered from COVID-19. Cells were cloned and their antibody genes were expressed, purified, and characterized to create recombinant human antibodies. Many of these have already been published and each is available in up to gram quantities.

Recombinant SARS-CoV-2 Spike S1 Protein ELISA
As the SARS-CoV-2 Spike S1 protein is displayed on the surface of the viral particles, antibodies that bind very specifically and with high affinity to the S1 protein can be used in immunological assays like ELISAs to detect the presence of the virus in biological samples. Each S protein contains two subunits, S1 and S2, with the S1 subunit mainly comprised of the receptor-binding domain (RBD). It is the RBD which is responsible for recognizing the cell surface receptor ACE2.
The SARS-CoV-2 Spike S1 Protein ELISA Kit is designed for the detection of SARS-CoV-2 Spike S1 RBD in a convenient 96-stripwell plate, enabling you to simultaneously process up to 96 samples in a single experiment. For added convenience and a more quantitative interpretation of the results, the kit also includes recombinant Spike S1 RBD which enables you to build a reference standard curve.
SARS-CoV-2 Spike S1 Protein ELISA Kit – validated for biological samples including saliva and plasma.
Recombinant SARS-CoV-2 Spike S1 protein generates reliable, consistent standard curves.
Recombinant SARS-CoV-2 Proteins
Active Motif manufactures our own high-quality recombinant proteins, including SARS-CoV-2 spike S1 proteins, and a number of SARS-CoV-2 nonstructural proteins (NSPs). Each of these proteins is available in up to 1 mg quantities that are in stock and ready to ship. Contact us to inquire about bulk orders.
