As the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic rages on, several virus variants have been emerging with mutations in the structural and non-structural proteins. The ...

Panel A shows the lineage of mutations that have been identified in the omicron BA.1, BA.2, BA.2.12.1, and BA.4 or BA.5 subvariants of SARS-CoV-2, as compared with the reference WA1/2020 isolate. BA.4 ...

Panel A shows the mutations of the omicron BA.1 and BA.2 sublineages in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein. Panel B shows neutralizing antibody titers that ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

The research group found that organic molecules with helical shape undergo a unique electron-transfer reaction by acid and base stimuli in a reversible way. These molecules have excellent properties ...
