The materials used include gloves, a micropipette, sterile pipette tips, a hot water bath, ice, centrifuge tubes, sterile loops, E. coli colonies, and various petri dishes containing Luria Bertani agar, ampicillin, and arabinose.
Before beginning make sure to put on sterile gloves that fit, as they will be required to be worn for the entire lab due to the bacteria being worked with. First obtain two centrifuge tubes, then label them with either your name or initials. One tube will be positive for pGLO, the other will be negative, label this accordingly onto each tube as well. Load a fresh tip onto the pipette, and transfer 250µL of the transformation solution into the tubes. Seal the tubes and place them in ice. Next, obtain a sample of bacteria …show more content…
Again using a new sterile loop, submerge the new loop into the tube labeled to indicate pGLO is present. Add this sample to the positive pGLO tube only, do not add it to the negative pGLO tube. Dispose of all loops into the red bag, if unsure of its location ask the TA. Allow both the tubes to rest in ice for 10 minutes. During this time, obtain 4 petri dish plates from the TA. One LB plate, two LB/amp plates, and one LB/amp/ara plate. LB stands for Luria Bertani, the broth medium used to grow the bacteria. Amp is short for ampicillin, and ara is short for arabinose. The LB plate should be labeled as negative pGLO, as should one of the LB/amp plates. The other LB/amp plate and the LB/amp/ara plate should be positive for pGLO. After 10 minutes, remove the tubes from the ice and submit them to the hot water bath for 50 seconds, leaving as little time between transfers as possible. Afterwards, place the tubes back on ice immediately for 2 minutes. With a fresh tip each time, add 250 µL to each tube, then let them sit for 10 minutes. After this 10 minutes, mix the contents by flicking the tube, then using a fresh tip for each tube pipette 100 µL of each into their respectively labeled petri plates. Using a sterile loop

...The purpose of this lab was to genetically transform bacterial plasmid DNA with foreign pieces of DNA, pGLO, that causes expression of an ampicillin resistant gene, and see the effects it has on bacterial growth in presence of the antibiotic, ampicillin. We inserted pGLO DNA into the genome of the bacteria through the use of inoculation loops, Laurel Broth, transformation solution, and procedures such as heat shock and incubation. This experiment involved four bacterial agar plates, two of which we genetically transformed (experimental groups; +pGLO LB/amp/ara and +pGLO LB/amp), and two of which we did not genetically transform and were control plates (-pGLO LB and -pGLO LB/amp/). Out of the two genetically transformed bacteria, only the bacteria containing arabinose sugar (+pGLO LB/amp/ara) initiated expression of the GFP (Green Fluorescent Protein) gene, causing the bacterial...

Pglo Transformation Lab Report

...The materials used in the transformation of Escherichia Coli include a transformation solution, a starter plate of bacteria colonies, and pGLO. A bacterial suspension is created by transferring 250 μl of transformation into two sterile 2.0 microcentrifuge tubes of different colors. One of the tubes is labeled +pGLO and the other is labeled –pGLO. Once 250 μl transformation solution is in each of the tubes they are placed on a round floating tube rack and then placed on ice. To complete the bacterial suspension, 2 large or 3 small colonies of bacteria are taken from the starter plate using a sterile loop. Holding the +pGLO tube between two fingers, the loop with the bacterial colonies is placed in the transformation solution. To ensure that the entire colony is completely dispersed in the transformation solution the loop is spun vigorously until there are no floating chunks remaining in the solution. Using a new sterile loop, this same process is...

Formal Lab Report 2

...Biology Formal Lab Report 2 Intro Throughout this lab, the main topic is genetic transformation. Genetic Transformation is a phenotypic change caused by genotype change from transferring foreign genes into an organism. This lab is to transform the bacteria E.Coli with the GFP gene (Green Fluorescent Protein). GFP makes organisms glow in the dark with UV light, similar to jellyfishes.GFP will be transferred into E.Coli through the use of recombinant DNA, or simply a vector. A vector is a plasmid that transfers foreign DNA into cells. Bacteria can transfer plasmid to other bacteria so they can survive and adapt to the environment they are in. The pGLO plasmid includes the GFP gene (allows bacteria to glow), Beta-lactamase (resists ampicillin), ORI sites (allows bacteria to self replicate), and AraC (allows induction of GFP gene). Materials and Methods: In this lab, first there will be two micro test tubes, one labled pGLO+ and the other pGLO-. Using a sterile transfer pipet, transfer 205 microliters of CaCl2 into each tube. Then put the tubes on ice. Then use a sterile loop to pick up a single colony of bacteria from the starter plate. Put the colony in the pGLO+ tube and spin the loop. Then put the tube back in ice. Repeat this for the pGLO- tube with a new sterile loop. Next use a new sterile loop and get some DNA stock. With the loop, immerse it in only in the pGLO+ tube. After that, incubate the tubes in ice for 10 minutes. Label one plate LB/amp +pGLO, another LB/amp/ara...
