Does the amino acid sequence of SARS-CoV-2 Spike RBD (multimeric) (319-591) Recombinant Protein (8xHis-Tag) #17862 (319-591) being longer than the amino acid sequence of other RBD products (318-541) affect its binding activity with ACE2?

The additional amino acids found in SARS-CoV-2 Spike RBD (multimeric) (319-591) Recombinant Protein (8xHis-Tag) #17862 should not affect the binding of RBD to ACE2 because the RBD region ends at amino acid 527.
