EpiGentek offers a full collection of proteins dedicated to the research of COVID-19. Proteins are heavily involved in the structure and function of coronaviruses. COVID-19/SARS-CoV-2 is made up of two main proteins: spike proteins (S-proteins) and nucleocapsid proteins (N-proteins). S-proteins are involved in viral attachment and cell entry, making them an important diagnostic target. N-proteins are involved in creating the viral capsid, and can be used as a marker for diagnostic assays.
