A doctor from Overlake Hospital knows that you have been working with bovine pancreatic cells. He wants you to take a look at the proteins expressed in the cells of the pancreas of a 54 year old patient that has a pancreatic tumor. What method will you use to roughly estimate how many proteins are expressed in those tumor cells? Hint: there are lots and lots of proteins. Hint: you can't do it by just running your sample on a gel.

To correctly perform and interpret proteomic analysis, careful attention to the following may be needed: - Proteins' compositions can be influenced by pH, hypoxia, anesthesia treatment, or other environments, which may influence the outcome of an experiment. - The myriad ways proteins can be processed and modified. - The large range of protein abundances observed, spanning 10 to the power of 10 orders of magnitude in eukaryotes. - Selecting among the numerous PCR protocols for amplifying the naturally observed proteins.

You are conducting a research project in which you are investigating the response of a mammalian cell line in culture to a novel candidate anti-cancer drug. Analysis of the secretome will provide very important biochemical information to understand the cellular response to the drug. Give a detailed overview of how you would combine 2-dimensional electrophoresis and/or multi-dimensional separations with Mass Spectrometry to obtain information on the secretome, through proteomics and glycomics approaches (Min 2 and a half pages).

You just cloned a new gene from mice. Which of the following techniques would be the BEST choice to use if you wanted to determine if this same gene/DNA was present in a human sample? Northern blot analysis Restriction enzyme analysis Western blot analysis Southern blot analysis Agarose gel electrophoresis Place the steps in the protein production workflow in the correct order: Upstream processing Downstream processing Preservation Verification 1, 2, 3, 4 2, 3, 4, 1 4, 3, 2, 1 3, 4, 2, 1 2, 1, 4, 3 Which of the following statements about the human genome is INCORRECT? Human genomes are approximately 99.9% identical. Histone acetylation in the human genome is an epigenetic modification. Less than 2 percent of the genome codes for proteins. The human genome contains approximately 100,000 individual genes. The functions of at least 40 percent of human genes are still unknown.
