E23. In the Western blot shown here, proteins were isolated from redblood cells and muscle cells from two different individuals. Oneindividual was unaffected, and the other suffered from a diseaseknown as thalassemia, which involves a defect in hemoglobin. Theblot was exposed to an antibody that recognizes B globin, which isone of the polypeptides that constitute hemoglobin. Equal amountsof total cellular proteins were added to each lane.Lane 1: Proteins isolated from normal234red blood cellsLane 2: Proteins isolated from the redblood cells of a thalassemiapatientLane 3: Proteins isolated from normalmuscle cellsLane 4: Proteins isolated from themuscle cells of a thalassemiapatientExplain these results.

This is an SDS-PAGE of an antibody purification sample with IgG seperated from a Bovine Calf serum. Would you be able to describe the bands that are appearing and why it appeared on the gel this way? As well, a western blot was done after the SDS-PAGE and the bands that appeared were at 50 kDa and 150 kDa for the IgG and two elution lanes. May you please explain?
Various antimicrobial drugs to treat microbial infection have diverse mechanism of action. Consider the following antimicrobial drugs: A. Seconeolitsine, known as DNA topoisomerase I inhibitor in bacteria. (i) Explain briefly how inhibiting DNA topoisomerase I is a good mechanism of action for an antibiotic, include possible molecular machineries being targeted. (ii) What would be an appropriate response if seconeolitsine works well by stating the state of supercoiling in bacteria. (iii) To prove your answer (ii), you test the condition of bacterial DNA by running gel electrophoresis, one has been treated with seconeolitsine (+ sample) and the other one is not (- sample). Explain the position of each + sample and – sample band on the gel in reference to the point of origin (where you load your samples) or how far each DNA sample travel across agarose gel. (iv) Explain why you would expect answer (iii) for each + sample and – sample. B.…

To produce a specialized-transducing mycobacteriophage construct, a cosmid bearing the allelic exchange substrate is electroporated in Mycobacterium smegmatis, followed by an incubation at 30°C. True/ False 2. A recombineering system involves the over-expression of recombinase proteins, which allows the use of a short DNA fragment as allelic exchange substrate, but can also be combined with the use of a mycobacteriophage construct. True/ False
Analysis of a 49kDA protein is aimed with a western blot technique. For this purpose, "whole cell extract" was obtained from biopsy samples taken from three different individuals, and when their spectrophotometric measurements were made, their concentrations were determined to be 40 µg/µL, 50 µg/µL, and 100 µg/µL for three samples, respectively. At the beginning of the experiment, 200 µg of protein is loaded into each gel well by using a ready 5x loading solution containing SDS and β-mercapta-ethanol together with glycerol and methylene blue dye. a) If loading will be done in a volume of 20µL, then how is the preparation of the samples before loading?b) Considering the loading content given above, what can be said about whether this PAGE is "non-denaturing" or "denaturing". Justify taking into account the loading solution content.
Give three reasons why liposomes/nanoparticles are attractive drug delivery system for recombinant protein preparations?
What is the purpose of washing a western blot membrane with TBST after the primary antibody binding and before substrate addition? To remove excess antibody that is not bound to the protein of interest O To remove the protein of interest from non-specific binding pockets of the membrane. There is no purpose, this is not an important step and may be skipped. To remove the HRP from the primary antibody, allowing for greater accuracy of signal presence.
Several vaccines against viral infections are made by isolating purified surface proteins of the viral particle, mixing them with an adjuvant to stimulate an innate immune response, and injecting the mixture into people. Two examples of this are the vaccine against Hepatitis B virus, and the vaccine against Human Papilloma Virus (the ‘cervical cancer’ vaccine). One interesting property of vaccines of this type (known as ‘subunit vaccines’) is that there is a requirement for a CD4 T cell response to the vaccine antigen in order to generate antibodies to the innocuous protein in the vaccine. In the case of the Hepatitis B vaccine, the viral protein included in the vaccine is the Hepatitis B surface antigen (HepB-SAg), a protein that is approximately 200 amino acids in length. The graph in Figure Q4.27 shows the data from immunizing individuals with this vaccine, and monitoring their production of protective antibody responses to the viral protein. a) What results would be predicted if…
Following SDS-PAGE, what is an advantage of protein detection by immunoblotting (western blotting) over a non-specific gel-staining procedure? Under what circumstances would it be desirable to nonspecifically stain the gel, rather than immunoblotting?
Cell line A was cultured in the absence and presence of KB9520 or PPT. You then lyse the cells and fractionate them, generating membrane, cytosolic and nuclear protein fractions of the whole cell lysate. Western blots were then run using antibodies against ER (alpha) and ER (beta) for each treatment, and include different lanes for the membrane, cytosolic and nuclear protein fractions. Draw the expected results for these western blots and briefly discuss the expected differences.
