A new bacterial two-hybrid assay to study SARS-CoV-2 interactome

Recently, scientists have developed a bacterial two-hybrid (B2H) system to study the PPIs of SARS-CoV-2 in a heterologous non-eukaryotic system. This study is available on the bioRxiv* preprint server. Put simply, the B2H system could be used to analyze the SARS-CoV-2 proteome.

Research finds different antibody responses following COVID vaccination and natural infection

A new study published in the journal Nature attempted to investigate memory B cell evolution 5 months after vaccination with mRNA vaccines such as Moderna (mRNA-1273) or Pfizer-BioNTech (BNT162b2) in SARS-CoV-2 naïve individuals. The study explored various aspects of memory B cell antibody response like neutralizing response, affinity, epitope targeting, and neutralizing breadth.
