Use a sterile loop to pick up several colonies of bacteria from the starter plate. Traditional Heat Shock Transformation. HYPOTHESES: The experimental hypothesis is that on plates containing no antibiotic, bacteria with or without the plasmid can survive, and so both will grow lawns of bacteria. 2014). In this lab, students will: Transform bacteria using a plasmid containing a jellyfish gene. How is heat shock used to introduce plasmids into bacterial cells? 5. In this investigation, students will first acquire the tools to transform E. Because of this, nearly all plasmids (even those designed for mammalian cell expression) carry both a bacterial origin of replication and an antibiotic resistance gene In artificial transformation, bacterial cells should be susceptible under certain laboratory conditions prior to transformation. This can be done by dragging the loop across the plate so that it lightly scrapes the colonies off the surface. The pGLO Bacterial Transformation Kit for General Biology is a three-dimensional approach to the classic transformation lab.
