Antibody Testing

IgM/IgG/IgA Antibody Detection Kit (Indirect ELISA) Pipet

Antibody screening has important public health uses in determining immunity to and prevalence of COVID-19, as well as identifying who has been infected and evaluating potential blood based therapeutics. Detect IgG, IgM, and IgA antibodies to SARS-CoV-2 N and S1 RBD proteins in serum, saliva, and dried blood samples using the indirect ELISA kits.

COVID-19 Indirect ELISA


The spike protein (S-protein) and nucleocapsid protein (N-protein) are encoded by all coronaviruses, including SARS-CoV-2 that was first detected in Wuhan City, China, in December 2019. Both recombinant forms of these proteins are now available from RayBiotech to advance infectious disease research.

Monoclonal & Polyclonal Antibodies to SARS-CoV-2

COVID-19 Antibodies


Anti-SARS-CoV-2 N-Protein Aptamer

Frequently referred to as "synthetic antibodies", aptamers are single stranded DNA molecules which can specifically recognize and bind to the targeted protein. Multiple modifications available. Aptamer selection was done against recombinant SARS-CoV-2 protein (cat# 230-30164).



PCR Tests for SARS-CoV-2

RayBiotech's innovative PCR kits allow rapid, convenient detection of SARS-CoV-2 nucleic acids. Our protocols offer unique advantages, such as enabling the researcher to skip laborious RNA extraction, or to avoid PCR machines entirely, and detect the virus by visual color inspection.

COVID-19 Patient Samples

Different sample types from COVID-19 patients, including serum/plasma, PBMCs, dried blood spots, & more. Serum/plasma from non-COVID-19 patients also available.

Sample Collection Kits for COVID-19 Research

Saliva and dried blood sample collection kits for RNA, DNA, Antibody and Protein analysis in normal (non-COVID-19) and COVID-19 samples.


Binding AssayPipet

COVID-19 Spike-ACE2 Binding Assay Kit

The entry of the SARS-CoV-2 virus into host cell is mediated by an interaction between the Spike (S) protein’s receptor binding domain (RBD) on the surface of the viral particle and the Angiotensin I Converting Enzyme 2 (ACE2) receptor on the human cell surface. As such, this binding event is a biological target for COVID-19 therapies. The RayBio® COVID-19 Spike-ACE2 binding assay kit allows the researcher to rapidly screen and identify small molecules, antibodies, or other biological molecules that potentially interfere with the formation of the S-ACE2 complex.

Sandwich ELISA KitsPipet

Sandwich ELISA kits for detecting N- and S- proteins to SARS-CoV-2. Also offered is a sandwich ELISA for Human ACE2, an endogenous membrane protein that enables COVID-19 infection. Indirect ELISAs for IgG, IgM, and IgA antibodies to SARS-CoV-2 can be found in the above 'Antibody Testing' section.


Multiplex Protein ArrayPipet

Semi-quantitative detection of IgM and IgG antibodies in serum or plasma to the SARS-CoV-2 (COVID-19) spike (S) protein.
