It's the end of 2021, and our video resources continue to be very popular for our educators, not only for aiding their pre-lab preparation, but also for preparing their students before performing the experiment! So, without further ado, here are…

What is transformation efficiency and why is it important?

Transformation is highly inefficient—only one in every 10,000 cells successfully incorporates the plasmid DNA. However, since a billion cells are used in a transformation experiment, only a few cells must take up the plasmid to achieve a positive outcome. We can use the data from our experiment to calculate the transformation efficiency!
