Identifying an Unknown Plasmid Through the Process of Gel Electrophoresis Introduction: Biotechnology requires certain techniques and methods that help identify plasmids, which can be used for forensics, DNA fingerprinting, etc. In this class, each lab focused on teaching the process of using the correct techniques used to identify a plasmid. Plasmids are pieces of DNA that are circular and relatively smaller than chromosomes. They aren’t important in the sense that they don’t carry out…

Distinction Between Gel Nails vs Acrylic Nails Gel Nails vs Acrylic Nails Women always want to look great and with this thought, businessmen and producers allow us many items to focus on women’s needs. Â Fashion add-ons like bags, footwear, jewellery as well as nail improvements can be found in most boutiques and stores all over the world. Nail extensions, artificial nails, fake nails or whatever you might like to call these add-ons are quickly becoming a trend. Â They're covers for that…

a little bit of bubbles, but we tried to get rid of it by pipetting it out of the tube which was a big error. Doing that, made us not have enough master mix later on to add it to our extracted DNA and the negative control tube so when we looked at out gel under the light, we had no bands for negative…

two-dimensional gel electrophoresis The blood samples were centrifuged at 1,500 rpm for 15 min at 4°C; plasma was isolated and stored at -80°C. Sample preparation was carried out by removing salt from the plasma by centrifugation and concentrated using 3 kDa amicon columns (Merck Millipore, USA) [16]. Two-dimensional gel…

These results reflect acceptability by the patients. FTIR Study FTIR spectra of silymarin, plain PLO gel and drug loaded PLO gel are showed in Figure 1. FTIR spectra of silymarin loaded PLO gel showed that the characteristics peaks of silymarin appear without any change in the spectrum of the drug. These results indicated that there was no interaction could be detected between the drug and the components…

Introduction: Bacteria create an enormous domain of prokaryote microorganisms that are diverse and abundant in most habitats on Earth. In fact, bacterial cells drastically outnumber somatic cells just on the external part of the human body compared to somatic cells within the whole body of a single individual. Bacteria are found just about anywhere on earth and are usually alongside other microorganisms including: mold spores or yeast cells, creating some difficulty when trying to distinguish…

Fat is a Drosophila tumour suppressor gene that regulates the growth of cells in tissues. The McNeill lab are trying to understand how Fat restricts growth and controls Hippo pathway activity. This is being tested using flies and mice. They are also investigating how Fat regulates growth via control of metabolism and mitochondrial function. The McNeill lab is hoping to find how Fat regulates the growth rate and full grown size of organs. Fat also controls a high-level form of tissue…

PCR machine to amplify DNA samples. Once the PCR cycle was complete, samples were stored in a freezer at -20⁰C. With the products from PCR, students used Gel Electrophoresis to separate electrically charged molecules. Gel Electrophoresis requires 3 steps; preparing a gel solution, gel electrophoresis, and photographing the gel. To prepare the gel, students mixed .3g of agarose and 30mLs of 1X TAE buffer in a 125 ml flask (Penn State Biology 220W Lab Manual, pgs.55-59). The mixture was microwaved…

highly cross-linked silicone which is blended with amorphous silicone [1]. Within the envelope is a gel comprising of both dimethyl- and methylvinyl-siloxane, forming a three-dimensional polymer network. There are three main implant generations; the first was produced between 1963 and 1972.…

subunits each having a molecular weight of about 80 kilo-Daltons. The third fraction, which contained the last elution material, had a band on the SDS-PAGE gel at around 72 kilo-Daltons. Although alkaline phosphatase has a similar molecular weight it also consists of two subunits making each subunit only 40 kilo-Daltons. Unfortunately the gel bands for wells 8 and 9 were not clear and therefore unable to be…
