The amazing green fluorescent protein Events leading to the cloning and expression of its gene and reflections on its impact By Milton J. Cormier and Richard O. McCann Only Mother Nature could construct a molecule whose fluorescence quantum yield approaches percent when dissolved in water.

This characteristic of green fluorescent protein is the reason its gene has revolutionized cell biology. The use of the GFP gene is responsible for advancing our knowledge of mechanisms in many areas of cell biology, such as gene expression, cell division, cytoskeletal organization, vesicle trafficking and neurotransmission.

Many of the details leading to the cloning of the GFP gene from the laboratory led Gfp bunny essay Milt Cormier one of the authors never have been reported.

Because of the importance of the GFP gene, we feel that these details may be of interest to the scientific community. From enzymology to molecular biology Cormier began his graduate work at the University of Texas at Austin under the guidance of Lester Reed and obtained his Ph.

While at Oak Ridge, see Cormier et al and Bernard Strehler et al discovered two of the components required for light emission in luminous bacteria. During his stay at Oak Ridge, Cormier had the pleasure of meeting many well-known scientists from various parts of the world as a result of the famous Gatlinburg Conferences held each year during this time.

Starting in the late s, the goal of the research program in the Cormier lab at the University of Georgia was to understand the biochemistry and biophysics of light emission in bioluminescent marine invertebrates, with the major focus initially on the sea pansy Renilla reniformis, which is an anthozoan soft coral common along the Georgia coast.

During the s, Bill Ward was a postdoc in the lab. He is now a professor at Rutgers University in New Jersey. Harry Charbonneau was a graduate student at the time and is now a professor at Purdue University in Indiana.

Over several summers, the three of them went to the University of Washington Marine Laboratory in Friday Harbor to collect the bioluminescent jellyfish Aequorea victoria.

In that period, thousands of jellyfish were collected and processed, and the extracts were frozen on dry ice for transportation back to the laboratory in Georgia. By the late s, members of the Cormier laboratory had isolated and characterized the three major proteins involved in bioluminescence in Renilla reniformis: It became apparent that we would never be able to isolate sufficient amounts of these Renilla proteins in order to study their structure—function relationships required for bioluminescence.

We had to take a different approach. There were by then two examples of the cloning of genes in higher organisms. One was the cloning of the gene coding for human insulin.

So Cormier decided to change his lab from an enzymology lab to a molecular biology lab. Since Charbonneau had made significant progress in determining the amino-acid sequence of aequorin, an attempt to clone the aequorin gene seemed logical.

This was before the facile cloning of your favorite gene was a routine procedure in every lab: From the partial amino-acid sequence of aequorin, we were able to derive oligonucleotide probes that were used subsequently to identify putative aequorin clones.

At about this time, the National Science Foundation grant that supported the Cormier lab was up for renewal, so Cormier submitted a new grant proposal to support the cloning work. For the first time in 25 years, his funding request was denied.

Fortunately, Cormier had a contact at a major pharmaceutical firm who seemed interested in the project. After he presented a seminar to the company, it offered generous support for the cloning work. At that point, Cormier began looking for a molecular biologist who could help clone the aequorin gene.

Doug Prasher, then a postdoc in the UGA genetics department, was interested and agreed to join the Cormier lab in the early s. By the time Prasher arrived, everything was in place for molecular biology, including some frozen Aequorea tissue.

By the autumn ofPrasher felt that he had isolated the aequorin gene based on the hybridization of the aequorin-specific oligonucleotides to several clonal isolates, but he could not verify this, because he was having difficulty in expressing the gene. We had a conversation about this problem.

This characteristic of green fluorescent protein is the reason its gene has revolutionized cell biology. The use of the GFP gene is responsible for advancing our knowledge of mechanisms in many areas of cell biology, such as gene expression, cell division, cytoskeletal organization, vesicle trafficking and neurotransmission. The green fluorescent protein (GFP) is a protein composed of amino acid residues ( kDa) that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range. [2] [3] Although many other marine organisms have similar green fluorescent proteins, GFP traditionally refers to the protein first isolated from the. Curatorial essay how to write The Edunia Seed Pack Studies, a group of lithographs, alludes to the visual convergence of roots and the flowerheads veins. What is rushing through the veins of the Edunia flowerheads is the blood of the artist, transcoded and abstracted in phylogenetic expression.

McCann suggested Prasher might be expressing aequorin at a low level even from pBR, which was an early cloning vector in which inserts were cloned into either ampR or tetR genes but not an expression plasmid, and that this could be measured in E. We suggested Prasher look for expression using a bioluminescence assay used routinely in the lab.

The very first try produced so much light that the luminometer became saturated. There was jubilation in the lab. We knew then that we had expression of aequorin. That paper was published in Furthermore, Ward was willing to furnish us with partial amino-acid sequence data.

Prasher agreed and was successful in isolating a GFP clone. When the gene was sequenced, we realized that the clone represented 70 percent of the coding sequence. Since Prasher could not identify the full-length gene in that cDNA library, it was obvious that additional collections of Aequorea were required.We will write a custom essay sample on A Dual-Criticism Look at The Birthmark specifically for you for only $ $/page.

Throughout the 20th century, eye-catching images effectively focused public attention on, for example, on NASA’s extraordinary achievements.

Other works, like GFP Bunny and GFP K-9, are potentially sweet and optimistic. The GFP Bunny project, although it has become very complex, is potentially pleasurable because it involves the animal’s socialization.
