Blue White Screening | CSIR NET- Life Sciences | GATE Exam

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. DNA of interest is ligated into a vector. The vector is then inserted into a competent host cell viable for transformation, which are then grown in the presence of X-gal. Cells transformed with vectors containing recombinant DNA will produce white colonies; cells transformed with non-recombinant plasmids (i.e. only the vector) grow into blue colonies. This method of screening is usually performed using a suitable bacterial strain, but other organisms such as yeast may also be used.

    Hello mam, here how we will differentiate between recombinant and non transformed cells. Self ligated cells will appear blue in colour but what about non transformed cells how it will be differentiated from recombinant cell. Please clearify

  • @Quolon

    White colour colonies because Lac z gene contains Cloning sites where our Gene of interest gets inserted resulting into disruption of Lac z gene. So now if lac z gene is disrupted, there will be no beta galactosidase production, and thus no conversion of X gal, and thus white colonies.

    This video is confusing. Transformation is necessary in every aspect. If there's no transformation we won't even get Blue colonies. Then comes Recombination, if your Plasmid Vector contains your gene of interest in the Lac z sequence, beta galactosidase won't be produced as the Lac z gene is disrupted by your Gene of interest thus you'll get white colonies. If your vector doesn't contain your gene of interest, that means the Lac z gene is intact which will produce beta galactosidase giving blue colour colonies. Recombinant- White colour colonies. Non recombinant- Blue colour colonies. And non transformants means bacteria didn't uptake your plasmid vector.
