SARS-CoV-2 Antigens and Antibodies-designed for Diagnostic Kit Development

Sekbio developed and produced SARS-CoV-2 related products. Targets include the Spike protein (S), N protein (N), and ACE2. Moreover, we also provide several products about coronavirus to meet the needs of scientific research.


The number of infected people in China has increased, and outbreaks have occurred in many countries. On January 30, 2020, the World Health Organization announced that the 2019 Novel Coronavirus (SARS-CoV-2) was listed as Public Health Emergency of International Concern (PHEIC). At this point, the SARS-CoV-2 (COVID-19) disease is a battle in China and a global battle.


Sekbio paid close attention to the progression of SARS-CoV-2. Once obtaining the virus gene sequence information, we quickly developed and produced SARS-CoV-2 related products.


IgG / IgM / IgA test materials

NP protein expressed in prokaryotic cells;

NP protein expressed in eukaryotic cells;

Spike RBD protein expressed in eukaryotic cells;

Spike S1 protein expressed in eukaryotic cells;

IgG, IgA, and IgM monoclonal antibodies for NP and RBD/spike antibody detection.


Antigen detection

Sekbio provides multiple antibody pairs to detect the COVID-19 NP protein, which can be used in luminescence and chromatography platforms. The sensitivity of using luminescence was ten pg/ml (verified by NP protein expressed in eukaryotic cells), and chromatography was 20 pg/ml.


Neutralizing antibody detection

Sekbio provides a variety of tags and mutated ACE2, which can bind to RBD or S1 Protein and develop a neutralizing antibody detection assay on the luminescent or chromatography platforms.
