Blue–white screen - Wikipedia

The blue–white screen is a screening technique that allows for the rapid and convenient detection of recombinant bacteria in vector-based molecular cloning experiments. This method of screening is usually performed using a suitable bacterial strain, but other organisms such as yeast may also be used. DNA of interest is ligated into a vector.


For screening, as defined, there is the second, economic, aim of achieving more for unit expenditure by saving the time of highly trained professional people.
