    SARS-CoV-2 Spike Glycoprotein (S2), Sheep Fc-Tag (HEK293)

    SARS-CoV-2 (formerly known as Novel Coronavirus 2019-nCoV) Spike Glycoprotein (S2) is a recombinant antigen which contains the Spike subunit 2 protein, amino acids 685-1211. Spike S2 protein is manufactured in HEK293 mammalian cells to obtain more authentic post-translational modifications, compared to other expression systems. SARS-CoV-2, previously known as the 2019 Novel Coronavirus (2019-nCoV), causes the pandemic COVID-19 disease. Horseradish peroxidase (HRP) conjugated protein is also available ready for use in various immunochemical assays including Western blotting, immunohistochemistry,  ELISA applications and double‐antigen bridging assays (DABA).

    SARS-CoV-2 Spike Glycoproteins (S1), Sheep Fc-Tag (HEK293/CHO Cell Duo Pack)

    This SARS-CoV-2 Spike Duo Pack contains recombinant subunit 1 (S1) proteins manufactured in both HEK293 and CHO cells, for comparative analysis of expression host-cell differences, including post-translational modifications (PTMs) such as glycosylation. These proteins can be used in conjunction to investigate glycan-dependent differences in ACE2 binding affinities and susceptibility to neutralization by monoclonal antibodies or polyclonal sera.
