SARS-CoV-2 Trimeric Spike, S1 and RBD Omicron proteins are now available!

We are keeping up with the virus by producing SARS-CoV-2 Omicron variant (B.1.1.529) as Trimeric Spike, S1 and RBD. All of these are produced recombinantly in CHO cells and shown to be functional. Furthermore, we will have Omicron version of Nucleocapsid protein available with P13L, del31-33, R203K and G204R mutations in few weeks.  

In response to COVID-19 pandemia, we have produced and purified recombinant SARS-CoV-2 antigens for all the variants of concern for diagnostic use, some even in gram quantities. These viral proteins are ideal to use as antigens in antibody discovery or as immunological tools to measure the concentration of virus-specific IgG, IgM or IgA antibodies in patient’s blood samples.
