Ok, this is just cool. New technique to study the brain, whereby neurons can be colored differently based on their expression of certain fluorescent dyes. It makes some awesomely pretty pictures, like so:
One or more gene constructs may be present in a single cell and the entirely random expression of these proteins in the cell cytoplasm creates the many possible colour combinations.
‘In some cells we see a greyish colour because all the proteins are expressed about equally. But in most cells the proteins are at different concentrations giving us a range of hues,’ Lichtman told Chemistry World.
I know immunologists who would kill to have their CD4s, CD8s, DCs, etc. light up like this.
