Figure 1: The G-quadruplex structure-specific antibody, BG4, binds with high affinity to RNA G-quadruplex structures. Here we show that a G-quadruplex-specific antibody, BG4 (ref. 4), binds to RNA ...

We have used size-fractionated, fluorescent dextrans to probe the structure of the cytoplasmic ground substance of living Swiss 3T3 cells by fluorescence recovery after photobleaching and video image ...

Small protein molecules almost do not experience the cytoplasm viscosity while moving within the cell. Scientists have now shown that the effect can be described universally to include ...

The current coronavirus disease 2019 (COVID-19) pandemic has claimed over 1.9 million lives so far, and scientists have been racing to develop vaccines that will curtail its spread. Most of these ...

The nuclear pore complex (NPC) mediates transport of all macromolecules between the nucleus and the cytoplasm. The structure of the NPC — a cylindrical ring-like structure lined with nucleoporins ...
