Researchers performed dSTORM (direct stochastic optical reconstruction microscopy) with several labeling techniques for visualizing and quantifying ACE2 receptor expression on various cells.
Some portions of the infamous coronavirus spike remained unchanged among variants, enabling certain rare antibodies to recognize all SARS-CoV-2 variants.
A recent PNAS journal study has sought to address the above-stated drawback and developed a new strategy that involves a self-assembling scaffold of proliferating cell nuclear antigen (PCNA). This technique can develop nanoparticles containing evenly incorporated heterotypic antigens.
