Molecular and Epidemiological Characterization of Emerging Immune-Escape Variants of SARS-CoV-2

The successive emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants has presented a major challenge in the management of the coronavirus disease (COVID-19) pandemic. There are growing concerns regarding the emerging variants escaping vaccines or therapeutic neutralizing antibodies.

Phosphopeptide enrichment using Phos-tag technology reveals functional phosphorylation of the nucleocapsid protein of SARS-CoV-2

Phosphorylation of viral proteins serves as a regulatory mechanism during the intracellular life cycle of infected viruses. There is therefore a pressing need to develop a method to efficiently purify and enrich phosphopeptides derived from viral particles in biological samples. In this study, we utilized Phos-tag technology to analyze the functional phosphorylation of the nucleocapsid protein (N protein; NP) of severe respiratory syndrome coronavirus 2 (SARS-CoV-2).

Persistence of robust humoral immune response in COVID-19 convalescent individuals over twelve months after infection

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection elicits varying degrees of protective immunity conferred by neutralizing antibodies (nAbs). In this study, we report the persistence of nAb responses over 12 months after infection despite their decreasing trend noticed from 6 months.
