Figure-2: Western blot analysis of recombinant SARS-CoV-2 Spike S1 N439K mutant protein. Anti-Spike S1 antibody was used in western Blot analysis.
Figure-3:Comparative binding of Spike S1 variants to sACE2: Wells of a 96-well microtiter plate were coated with 100 ng in duplicates each of S1-WT (Cat# 21-1008), S1-N439K (Cat# 21-1012), S1-D614G (Cat# 21-1009), S1-South Africa (Cat# 21-1017), and S1-Southern California (Cat# 21-1018). Binding to sACE2 was determined by adding different concentrations of biotinylated-sACE2 (Cat# 21-1006).

Amount : 100 μg
Purification : >95% by SDS-PAGE.
Content : PBS and 10% Glycerol.
Storage condition : SARS-CoV-2 Spike S1-His Protein is shipped on ice packs. Upon arrival, Store at -20°C. Do not freeze-thaw multiple times.
AA sequence : The target protein is expressed with sequence (AA 14-683) of SARS-CoV-2/COVID-19 Spike S1 sequence with mutation at 439aa (N439K) fused with a 10×His tag in C-Terminal.

Source: SARS-CoV-2 (2019-nCoV) Spike S1(N439K) in CHO-K1.The spike protein (S1) of coronavirus (CoV2) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
