T544 0-35 Sentence denotes nAbs Derived from COVID-19 Patients
T545 36-221 Sentence denotes Patients who have recovered from SARS-CoV-2 infection are one potential source of nAbs (Chen et al., 2020a, Ju et al., 2020, Walls et al., 2020, Wölfel et al., 2020, Yuan et al., 2020).
T546 222-452 Sentence denotes In an effort to obtain these nAbs, scientists sorted RBD-specific memory B cells and cloned their heavy and light variable regions to express recombinant forms of the corresponding antibodies (Chen et al., 2020a, Ju et al., 2020).
T547 453-614 Sentence denotes Four of the antibodies produced in these studies (31B5, 32D4, P2C-2F6, P2C-1F11) showed high neutralizing potential in vitro, and all inhibited ACE2-RBD binding.
T548 615-734 Sentence denotes Successful antibody-mediated neutralization of SARS-CoV-2 seemed to be dependent on the inhibition of ACE2/RBD binding.
T549 735-929 Sentence denotes However, Chen et al. showed that nearly all antibodies derived from serum of 26 recovered patients bound to S1 and RBD, with only three actually inhibiting ACE2/RBD binding (Chen et al., 2020a).
T550 930-1167 Sentence denotes Of note, a SARS-CoV-1-derived neutralizing antibody (47D11) (Wang et al., 2020a) and a single-chain antibody against SARS-CoV-2 (n3130) (Wu et al., 2020c) have also been shown to neutralize SARS-CoV-2 without inhibiting ACE2/RBD binding.
T551 1168-1258 Sentence denotes Thus, blocking this interaction may not be a prerequisite for an effective SARS-CoV-2 nAb.
T552 1259-1503 Sentence denotes The generation of a hybridoma producing a monoclonal nAb against SARS-CoV-2 provides the potential for a therapeutic Ab that can be directly administered to patients to block ongoing infection and potentially even as a prophylactic (Figure 6D).
