[PDF][PDF] Potent SARS-CoV-2 neutralizing antibodies directed against spike N-terminal domain target a single supersite

…, J Yu, F Bahna, J Bimela, Y Huang, PS Katsamba… - Cell host & …, 2021 - cell.com
Numerous antibodies that neutralize SARS-CoV-2 have been identified, and these generally
target either the receptor-binding domain (RBD) or the N-terminal domain (NTD) of the viral …

[PDF][PDF] Cryo-EM structures of SARS-CoV-2 spike without and with ACE2 reveal a pH-dependent switch to mediate endosomal positioning of receptor-binding domains

…, M Rapp, G Cerutti, GY Chuang, PS Katsamba… - Cell host & …, 2020 - cell.com
The SARS-CoV-2 spike employs mobile receptor-binding domains (RBDs) to engage the
human ACE2 receptor and to facilitate virus entry, which can occur through low-pH-endosomal …

Analyzing a kinetic titration series using affinity biosensors

R Karlsson, PS Katsamba, H Nordin, E Pol… - Analytical …, 2006 - Elsevier
The classical method of measuring binding constants with affinity-based biosensors involves
