SARS-CoV-2 S1 protein NTD (L18F, T20N, P26S, D138Y, R190S), His Tag (MALS verified)

SARS-CoV-2 S1 protein NTD, His Tag (S1D-C52He) is expressed from human 293 cells (HEK293). It contains AA Ser 13 - Leu 303 (Accession # QHD43416.1). The L18F/ T20N/ P26S/ D138Y/ R190S mutations were identified on the spike protein N-terminal domain (NTD) in the SARS-CoV-2 Gamma variant (Pango lineage: P.1; other names: 20J/501Y.V3).
