A way of characterizing an aqueous solution within a cell surrounded by membrane is discussed. As an example, a preliminary experiment involving supercooling and freezing of water extracellularly is summarized, on normal plant cells. Reasons are given for supposing that such an experiment could, at...
but because small molecules can enter cells easily, they aren’t that specific and often have unwanted side effects. Large molecules such as proteins can have much more specific and powerful effects than small-molecule drugs, but they can’t cross a cell membrane and enter a cell, greatly ...

Cellular membrane-less compartment formation of these FUS proteins was examined by expressing mCherry (mCh)-fused FUS variants in cells. Consistent with the in vitro protein solution test, more protein condensates (red puncta) were observed with longer FUS proteins in diverse cell lines (Fig.1aand...
Under a Creative Commons license open accessAbstract Cell membrane camouflaged nanoparticles have been widely used in the field of drug leads discovery attribute to their unique biointerface targeting function. However, random orientation of cell membrane coating does not guarantee effective and appropriate...
Most of the properties we associate with life are properties of the cytoplasm .Much of the mass of a cell consist of this semifluid substance ,with is bounded on the outside by the plasma membrane .Organelles are suspended within it ,supported by the filamentous network of the cytoskeleton ....

A number of C3-prenylated 4-hydroxyquinoline derivatives were produced by using cell extracts from the recombinant E. coli cells. For more details, see the paper by S.-M. Li et al. on p. 1724 ff.关键词: biosynthesis enzyme catalysis farnesyltransferase membrane-bound prenyltransferase ...
aouter limit of the cell. For organelles and vesicles surrounded by a single membrane, however, the face directed away from the cytosol—the exoplasmic face—is on the inside in contact with an internal aqueous space equivalent to the extracellular space. 细胞的外面极限。 为一个唯一膜和泡围拢...
