The global COVID-19 pandemic still rages around the world. It is well-known that the SARS-CoV-2 has an astonishing speed of mutation. It took just over a year to use nearly 1/2 of the Greek alphabet, and developed from Alpha to Lambda. Subsequently, the new variants spread like Beta in South Africa, Delta in India, and Lambda in Peru. CUSABIO produced the most popular mutant antigens, which will meet needs in diverse COVID-19 research in clinical and research labs.

SARS-CoV-2 Alpha

Recombinant SARS-CoV-2 Nucleoprotein (N)(R203K,G204R) (Active) (CSB-EP3325GMY(M12))

Its purity is greater than 96% as determined by SDS-PAGE.		Its binding ability measured by functional ELISA with N Mouse Monoclonal Antibody at 2 μg/ml, of which EC50 is 6.775-13.04 ng/ml.		Its binding ability measured by functional ELISA with N Recombinant Antibody at 2 μg/ml, of which EC50 is 4.664-8.256 ng/ml.

SARS-CoV-2 Delta

Recombinant SARS-CoV-2 Nucleoprotein (N)(D63G,R203M,D377Y) (Active) (CSB-EP3325GMY(M14))

Its purity is greater than 85.7% as determined by SDS-PAGE.		Its binding ability measured by functional ELISA with N Mouse Monoclonal Antibody at 2 μg/ml, of which EC50 is 3.834 - 5.294 ng/ml.		Its binding ability measured by functional ELISA with N Recombinant Antibody at 2 μg/ml, of which EC50 is 1.304 - 1.875 ng/ml ng/ml.

SARS-CoV-2 Gamma

Recombinant SARS-CoV-2 Spike glycoprotein(S) (E484K), partial (Active) (CSB-MP3324GMY1(M8)h8)

Its purity is greater than 90% as determined by SDS-PAGE.		Its binding ability measured by functional ELISA with human ACE2 at 2 μg/ml, the EC50 is 6.597-8.187 ng/ml.		Its binding ability measured by functional ELISA with Biotin-S Antibody at 2 μg/ml, the EC50 is 118.7 ng/ml.
