Y380Q novel mutation in receptor-binding domain of SARS-CoV-2 spike protein together with C379W interfere in the neutralizing antibodies interaction

The paper identifies a novel Y380Q mutation in the SARS-CoV-2 spike protein RBD, along with C379W, which may interfere with neutralizing antibody binding in early pandemic variants.

Pervasive transmission of E484K and emergence of VUI-NP13L with evidence of SARS-CoV-2 co-infection events by two different lineages in Rio Grande do Sul, Brazil

The paper investigates the spread of the E484K variant and identifies a novel lineage VUI-NP13L in Brazil, along with co-infection events between different SARS-CoV-2 lineages.

Comparison Of Different Kits For SARS-CoV-2 RNA Extraction Marketed In Brazil

This study compares four RNA extraction kits for SARS-CoV-2 detection via qRT-PCR, finding that magnetic beads and silica column methods perform best.

SARS-CoV2 quantification using RT-dPCR: a faster and safer alternative to assist viral genomic copies assessment using RT-qPCR

This study compares RT-dPCR with RT-qPCR for SARS-CoV-2 quantification, finding RT-dPCR provides higher precision and equivalent results across assays.
