Abstract

Protein precipitation is a commonly used unit operation in the process of isolating and purifying proteins. This project focused on the use of nonionic polymers to precipitate porcine hemoglobin. Elements of experimental design were used to select meaningful sets of experiments. The effects of various factors and two-factor interactions on the solubility of the protein were examined. The data indicated that higher weight polymers and higher concentrations of polymer both decrease porcine hemoglobin solubility, but the two-factor interaction between polymer concentration and molecular weight was an inconsistent interaction, resulting in higher solubility than would be independently expected. The role played by EO/PO fraction in solubility was also studied.

Biography

Clayton Buback was born in St. Charles, Missouri. At age 16, he enrolled in the Missouri Academy of Science, Mathematics, and Computing, and graduated at the top of his class, earning an Associate of Science Degree and High School Diploma simultaneously. He now attends the Missouri University of Science and Technology, and is working on two Bachelor’s Degrees: one in Biology, and one in Biochemical Engineering. Clayton will graduate from Missouri S&T in May of 2014, and will start medical school at the University of Rochester the following fall.
