In addition, immunogenicity of recombinant SARS-CoV-2 proteins and RBD–CRM197 fused conjugate, as well as characteristics of immune cell response when using aluminum hydroxide as adjuvant for immunization of mice were studied. It has been shown that the most immunogenic is N protein, and the least immunogenic is S protein RBD probably due to its low molecular weight. It was found that N protein, in contrast to the RBD, stimulates the expression increasing of in mouse splenic cells to increase the of IFN-gamma and to a lesser extent IL12b and IL-4, which indicates the activation of primarily cellular immune response.  Product Description popup.authors Horbаtiuk Oksаnа B.
