Fig 1: Sequence information of the S antigens of SARS-CoV-2. This figure contains all available information on the S antigens of SARS-CoV-2 used for the ELISpot assays. We modified an image by Miltenyi Biotec (https://www.miltenyibiotec.com/DE-en/products/peptivator-sars-cov-2-prot-s-107090.html#130-126-700, accessed on 29 June 2021), containing information on their PepTivator product and the protein sequence of SARS-CoV.2. The peptide mix (PepTivator) of the S protein (S1/S2) consists mainly of 15-mer sequences with 11 amino acids overlap, covering the immunodominant sequence domains of the surface glycoprotein of SARS-CoV-2. The peptide mix (PepTivator) of the S1 protein (S1) covers the complete N-terminus of the S antigen. The S1 Sino protein (http://www.sinobiological.com, accessed on 27 June 2021) is a recombinant protein expressed in (human) HEK293 cells.
