Lens Fiber Differentiation Experiment

Amazing Essays
Lens Fiber Differentiation and its effects on certain organelles.

This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used to approach the study (3) Results obtained; and, (4) Concluding both articles. Background Before one starts this scientific journey it is apparent the individual should have some basic knowledge regarding what lens fiber is and which part of the

Lenses and vitreous body were removed from the embryos from day 6-20. The vitreous body and lens are then transferred to a petri dish where they would be separated by doing a careful disection. Dr. Mark Adeelman donated the rhodamine-123 for the study which was used a methanol stock. This stock was used for the fluorescent probes. In order to be able to examine the lens with the confocal microscope one needs to stain it with the fluorescent dye. This process didn 't seem to work accordingly therefore another method was adapted lens slicing. Article two states that although cell on the outer layer of the slice was being damaged there were tons of cells located deep inside the cell that were able to examine. Rhodamine-123 was also used in this process. once the lens was stained with the rhodamine-123 it would enter stain the mitochondrial matrix. Next they rinsed the lenses with saline solutions for it to be looked under the confocal microscope to view the mitochondria and nucleus. After staining the slice they treated the tissue with 4% formaldehyde and 0.05% ethidium bromide in a NaCl solution. In some of the experiments it was evident actin was visible under the fiber

    In both techniques, we will first cleanse the infected area on the face before swabbing a culture to avoid collecting normal microbiota as we only want the infected agent using aseptic technique. In order to identify the pathogen, we will cultivate, isolate, and then identify the pathogen. In the classical method, we will culture the specimen in an agar to achieve more growth. We can then look at the morphology of the cell shape, size, and arrangement through light microscopy. Sometimes, an infection can be diagnosed solely by the patient’s signs and symptoms.…

    The sphaeroplasts were then spun down using centrifugation, and the supernatant was removed, which presumably contained the contents of the periplasm. Once the periplasmic components have been collected, one method to obtain the cytoplasmic components is to lyse the cells, and then spin down any of the membrane fragments that are present (Thein et al., 2010); to do this we osmolytically lysed the cells by subjecting them to a hypotonic solution. We also added DNase at this point, which degraded the DNA that…

    fischeri chDNA. Lysing the pellet of A. fischeri required the hydrogen bonds, hydrophobic interactions, and Van der Waals forces to be disrupted. This was done by the detergent sodium dodecyl sulfate (SDS), which was present in the re-suspension buffer added and created protein-lipid-detergent complexes. Proteinase K is added to digest proteins and any nucleases that might damage the DNA (Peant and LaPointe, 2004). RNase is added to avoid impurities from RNA.…

    The role of the EDTA in this solution is to bind to the cations in the lipid bilayer, which weakens the cell’s envelope. At this rate, the EDTA limits the DNA from degradation. After adding this solutions, the group resuspend each tube by vortexing each tube. Vortexer is a machine that mixes small samples of liquids. Adjusting the pipette to 200 µl, we add the second Miniprep solution or MP 2.…

    This step allows the sample to flow back across the matrix screen and gives a second chance for the conjugate/antigen to bind with the antibody. Pick either the RIGHT or LEFT side of the machine and push the SNAP test in (with the LARGE sample well going in first); push until you hear a click. This step allows a "wash" to go over the matrix to remove any debris that may interfere with the results. A colorless solution then interacts with the enzymes. Each enzyme converts multiple molecules of these subsrates which creates that BLUE color you see on the results…

    It is also called differential staining because it differentiates among bacteria and can be used to distinguish between them based on the differences of cell wall structure. There are two major groups of bacteria, the gram positive staining cells and gram negative staining cells. In this procedure, the bacteria are first stained with crystal violet “basic stain”, and then treated with adding a mordant, iodine, which fixes the stain inside the cell. The stained cells are washed with a decolorizing agent, alcohol and then counterstained with…

    For each repeat, the suspension was swabbed on a blood agar plate for sterility control. It is critical to use correct reading method in measuring inhibition diameter, as suggested by CLSI handbook. For some plates, multiple rings appeared, the reading of inhibition zone was based on the inner ring, which should be readily distinguished with unaided eyes (CLSI, 2013). The results of inhibition diameter was compared with QC ranges for each antibiotics provided in CLSI standards (2015). A media can be validated only if all tested antibiotics gave inhibition ranges that fall into the QC…

    The lab instructor issued out a test tube labeled with letter ‘I’, which consisted of two unknown bacteria, Gram-positive or Gram-negative that were streaked from a pure culture. Sterile techniques were followed while performing precise instructions as stated in the referenced Laboratory Manual. Example 1: The first procedure performed was done by isolating a pure culture from the mixture onto a solid Trypticase soy agar (TSA) media. Sterile technique was done by flaming the loop until it turned red to ensure that there were no current bacteria on the loop avoiding contamination followed by rapidly flaming the neck of the test tube to prevent the entry and contamination of unwanted microbes. After inoculating the loop substance from the test tube labeled ‘I’ was removed.…
