SARS-CoV-2 Immunoassay Kits

Creative Diagnostics now offers immunoassay kits for direct detection of the new coronavirus and antibodies against SARS-CoV-2

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, previously named 2019 novel coronavirus or 2019-nCoV) disease (COVID-19) from China at the end of 2019 has become a global pandemic and an unprecedented public health issue.

Creative Diagnostics started developing a new test shortly after the outbreak had become known. Only a few weeks later, two ELISAs for the detection of Anti-SARS-CoV-2 antibodies of classes IgM and IgG and one ELISA for the detection of SARS-CoV-2 NP antigen were available. Both test systems are currently only available to research institutions as research-use-only products. Preparations for CE registration of these tests are underway.

Technical Specifications

DEIASL019 SARS-CoV-2 IgG ELISA Kit

Principle Indirect ELISA
Sample Type Serum/Plasma
Sample Volume 10 uL
Incubation Time 50 mins, 37 °C
Total Wash Steps 2

Principles of Testing: This kit is based on the principle of indirect method (ELISA) to detect the SARS-COV-2 IgG antibody in human serum or plasma. The SARS-COV-2 whole virus lysate antigen is pre-coated on the enzyme-labeled strips. Add the test sample and incubate it. The IgG antibody in the sample is bound to the antigen. Wash the plate to remove SARS-COV-2 IgG that does not bind to the coated antigen. Add the enzyme-labeled reagent for a second incubation. When a SARS-COV-2 IgG antibody is present in the sample, a "coated antigen-IgG antibody-anti-human IgG enzyme conjugate" complex will be formed. After washing the plate again, color reagent is added, and the HRP linked to the complex will catalyze the color The reagent reacts to produce a blue product, which turns yellow after the reaction is terminated; if no SARS-COV-2 IgG antibody is present in the sample, it does not develop a color. Measure the OD value on a microplate reader or enzyme immunoassay system, and determine the presence or absence of a SARS-COV-2 IgG antibody based on the OD value 

DEIASL020 SARS-CoV-2 IgM ELISA Kit

Principle Capture ELISA
Sample Type Serum/Plasma
Sample Volume 10 uL
Incubation Time 80 mins, 37 °C
Total Wash Steps 2

Principles of Testing: This kit is based on the capture ELISA to detect the SARS-COV-2 IgM antibody in human serum or plasma. The anti-µ chain monoclonal antibody is pre-coated on the microplate wells. Add the test sample and incubate it. The IgM antibody in the sample is bound to anti-µ chain monoclonal antibody. Wash the plate to remove SARS-COV-2 IgM that does not bind to the microplate wells. Add the enzyme-labeled reagent for a second incubation. When a SARS-COV-2 IgM antibody is present in the sample, a "anti-µ chain monoclonal antibody-human anti SARS-CoV-2 IgM antibody-SARS-CoV-2 antigen enzyme conjugate" complex will be formed.

DEIA2020 SARS-CoV-2 Antigen ELISA Kit

Principle Sandwich ELISA
Sample Type Serum
Sample Volume 25 uL
Incubation Time 90 mins, 37 °C
Total Wash Steps 2

Principles of Testing: The new Coronavirus (SARS-COV-2) antigen detection kit is based on the principle of a double antibody sandwich enzyme-linked immunoassay. The microplate is pre-coated with an anti-new coronavirus N protein antibody. When the serum and plasma to be detected contain the new coronavirus N protein antigen, it will bind to the specific antibody coated on the microplate. After the HRP labeled detection antibody against the new coronavirus N protein was added, an "antibody-antigen-enzyme labeled antibody" complex is formed. After adding the chromogenic substrate TMB, HRP enzyme will catalyze the color development. After terminating the solution, the microplate reader will determine the Absorbance value to determine the presence or absence of new coronavirus antigen in each test sample.

These ELISA Kit are available now.  We can offer this product under OEM conditions. For more information, contact the Creative Diagnostics customer service department at or by telephone: +1 (631) 624-4882.
