What is the purpose of the pGLO bacterial transformation lab?
pGLO Lab Kits utilize Bio-Rad’s pGLO plasmid, which encodes a green fluorescent protein (GFP), to enable instructors to give students a hands-on introduction to transformation, cloning, protein chromatography, and electrophoresis techniques.
How could you tell if the bacteria took up the pGLO plasmid on the LB amp ARA plate?
The bacteria on the (+) pGLO LB/amp/ara plate should appear whitish when exposed to normal, room lighting, but fluoresce bright green upon exposure to the long-wave UV light.
How would you be able to test if the colonies you observed on the LB only plates are ampicillin resistant?
How would you change the bacteria’s environment to best tell if they are ampicillin resistant? The best test would be to take some of the bacteria growing on the LB plate and streak them on an LB/amp plate. If the bacteria are viable on the LB/amp plate, then they are resistant to ampicillin.
Why is pGLO important?
The pGLO plasmid is an engineered plasmid used in biotechnology as a vector for creating genetically modified organisms. The plasmid contains several reporter genes, most notably the green fluorescent protein (GFP) and the ampicillin resistance gene.
What is pGLO quizlet?
What is pGLO? a type of genetically engineered plasmid that encodes the gene for GFP and a gene for resistance to the antibiotic ampicillin. Also incorporates a special gene regulation system that can be used to control expression of the fluorescent protein in transformed cells.
How does the pGLO bacterial transformation relate to Griffith’s mice experiment?
when a mouse was injected with nonvirulent and heat-killed virulent bacteria the mice did die. showing that something from the dead bacteria caused the nonvirulent bacteria to kill the host.
What is the process of bacterial transformation?
Key steps in the process of bacterial transformation: (1) competent cell preparation, (2) transformation of cells, (3) cell recovery, and (4) cell plating.
Do the bacteria on the pGLO LB amp plate 3 contain the GFP gene?
Bio-Rad’s unique pGLO plasmid contains the gene for GFP and a gene for resistance to the antibiotic ampicillin. pGLO also incorporates a special gene regulation system that can be used to control expression of the fluorescent protein in transformed cells.
Which transformation method is suitable for bacterial transformation?
Supercoiled DNA is most efficient for transformation compared to linear or ssDNA that has the transformation efficiency of <1%. During electroporation, the salts present in the preparation mix may lower transformation efficiency.
How is pGLO made?
In Bio 6B, you’ll work with the plasmid pGLO in a long series of experiments, using multiple techniques of molecular biology. This recombinant plasmid, created by researchers at Bio-Rad, combines a gene for green fluorescent protein (GFP), cloned from a jellyfish, with control elements copied from a bacterial operon.
What is the pGLO system?
The pGLO system incorporates an arabinose promoter which precisely controls expression of the GFP in transformed cells. Expression of the GFP gene can be turned on simply by including arabinose (a sugar) in the growth medium.
