Laboratory Exercise #3 Measuring Protein in Solution Abstract The purpose of this lab was to learn about the Biuret assay reaction to determine if it can detect proteins and amino acids; also‚ to understand the process of “salting out” proteins and how to determine the amount of protein in a solution. In order to do so‚ egg white and ammonium sulfate were mixed on ice and then put into the centrifuge. After PBS was added‚ the amount of protein could then be determined. After that‚ 14 test tubes

Future of Food Development of nitrogen based bombs during World War I led to development of nitrogen based chemical fertilizers. DDT was the hero of it’s generation. In 1970’s‚ Monsanto introduced Roundup. (herbicide) Monsanto spent $8 billion buying out seed companies. The first time Americans became aware that GMO’s were part of their everyday dietwas 2001. 80 – 90% of Americans want GMO labeled. GMO labeling is the key way we can trace health effects and get corporations

Carlie Haeffner Qualitative Analysis March 20‚ 2015 The purpose of this lab is to identify unknown ions in a solution by using a type of chemical reaction called precipitate reactions. The key to finding which ions are present in a solution is to form a precipitate which makes the ions “come out” in a reaction (McNeil‚ 2013-2014). Water is used in these experiments to act as a solvent. Since water is a polar molecule‚ the slightly positive and negative charges will sometimes pull apart molecules

Identification of Mystery Plasmids Abstract Plasmids serve as important tools in genetics and biotechnology labs‚ where they are commonly used make many copies of a particular gene. The aim of this experiment was to identify three mystery plasmids based upon their characteristics; such as size‚ antibiotic resistance‚ lacZ profile and conjugative properties. The results obtained showed that plasmid number2 was the pDSK519 plasmid and its size was 26229.58 Bp. Plasmid pDSK519 also was found to be
