AN assumption inherent in back-mutation experiments is that at the cell concentrations used ‘background’ prototrophs in a substantially auxotrophic population will be expressed quantitatively in the ...

Clonal growth experiments with polystyrene-attached HeLa cells indicate that analysis of clone size distribution in mammalian cells grown in vitro must be carried out within one plating experiment.

The plating experiment in this image shows how yeast strains vary in resistance to a drug. Different strains (horizontal rows) were grown at cell densities that decrease from left to right. Sensitive ...

Three laser experiments today: laser-induced electroless copper plating, laser-assisted electroplating on stainless steel, and laser-induced chemical liquid phase deposition onto glass. Whoo! I'm ...
