pGLO Bacterial Transformation and GFP Kits 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.
What does pGLO do in transformation?
With the pGLO transformation kit, students use a simple procedure to transform bacteria with a gene that codes for Green Fluorescent Protein (GFP). The real-life source of this gene is the bioluminescent jellyfish Aequorea victoria, and GFP causes the jellyfish to fluoresce and glow in the dark.
What is the end result of bacterial transformation?
After transformation, bacteria are selected on antibiotic plates. Bacteria with a plasmid are antibiotic-resistant, and each one will form a colony. Colonies with the right plasmid can be grown to make large cultures of identical bacteria, which are used to produce plasmid or make protein.
What is the purpose and your hypothesis for the bacterial transformation lab?
Bacteria are microscopic, single-celled organisms. In this experiment, we will demonstrate and explore how to transform bacteria with new DNA so that it expresses different genetic information. The purpose of this lab is to explore the effets of bacterial transformation on e. coli bacteriums.
What was the purpose for including the pGLO LB plate as part of the experiment?
The purpose of spreading pGLO on the LB plate was to enable bacteria to grow, otherwise the ampicillin would kill them. If the pGLO is not spread, then the cells would be killed by the ampicillin.
Which is your control plate why pGLO?
What purpose does a control serve? Which control plate is not included in this experiment? The control plate does not contain the pGLO plasmid, but the other variables are the same. The control plate proves that the transformation is dependent on the presence of the pGLO plasmid.
Why is pGLO used?
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 the biggest benefit of transformation to the bacterial cell?
What is the biggest benefit of transformation to the bacterial cell? The bacteria might acquire genes that make it better able to survive in its environment.
How do we describe transformation in bacteria?
Bacterial transformation is a process of horizontal gene transfer by which some bacteria take up foreign genetic material (naked DNA) from the environment. Sometimes the exogenous genetic material may co-exist as a plasmid with chromosomal DNA.
What one plate would you first inspect to conclude that the transformation occurred successfully?
The plate that I would first inspect to conclude that the transformation was done successfully is the LB/Amp+plasmid. This is because for a transformation to be done effectively the foreign DNA must be inserted into the bacterial cell by a plasmid.
How will you know that the transformation was successful?
How can you tell if a transformation experiment has been successful? If transformation is successful, the DNA will be integrated into one of the cell’s chromosomes. Plant cells do not naturally take up DNA. Recombinant plasmids are either directly injected into cells or carried into the cell by an infecting bacterium.
What conclusions can you make when comparing the LB pGLO and LB AMP pGLO plates?
The LB/amp control plate can be compared to the LB/amp (+)pGLO plate. This comparison shows that genetic transformation produces bacterial colonies that can grow on ampicillin (due to the uptake of the pGLO plasmid and the expression of the ampicillin resistance gene).
What is the role of PGLO in bacterial transformation?
We know for a fact that pGLO is responsible for these changes because the original bacteria did not glow naturally (as we determined during the procedure) and because E. Coli without the pGLO were not able to survive in ampicillin.
Is the pGLO transformation Student Manual original to the experiment?
Paraphrased procedures have been synthesized from procedures found in the pGLO Transformation Student Manual. The pGLO plate observation chart was lifted from the pGLO Transformation Student Manual, but all data is original to our experiences. All pictures are original from the in-class experiment.
What is the purpose of the transformation lab?
The purpose of this lab was to study transformation and the effect that integrating certain genes into a typical E. Coli bacteria would have on the cell.
How does pGLO plasmid DNA transform E coli?
The E. Coli showed several changes when transformed by the pGLO plasmid DNA. The bacteria that incorporated the pGLO DNA into its own DNA was able to grow in conditions with ampicillin present, and glow under UV light.
