As you know, The COVID-19 has been rampant all over the world. CUSABIO, as a biotechnology company, always 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. Now, CUSABIO provides related antigen reagents (N protein and S protein), antibody reagents (N antibody and S antibody) and Nucleoprotein/ Spike glycoprotein IgG ELISA Kit with high quality.
