Reverse Protein Engineering Of Firefly Luciferase, Kahler Bugtong, Skyler Herczeg, Abraham Munoz, Alexandra Obata Jun 2014

Reverse Protein Engineering Of Firefly Luciferase, Kahler Bugtong, Skyler Herczeg, Abraham Munoz, Alexandra Obata

Bioengineering Senior Theses

Firefly luciferase is a bioluminescent protein commonly used as a bioluminescent tag in biological studies and applications. However, because the protein is fairly large in size, it is sometimes larger than the molecules it is intended to measure and is therefore not a sufficient tag in smaller applications. The active site of firely luciferase is also not well understood, making it difficult to engineer the protein without affecting its bioluminescent activity. In this paper, we discuss the experimental methods of Reverse Protein Engineering: a bioengineering technology that reduces the size of a protein while retaining its original function. This involves …

Characterization And Optimization Of Thermal Protective Fabrics Designed To Protect Against Splash Hazards, Jeremy Osguthorpe Jun 2014

Characterization And Optimization Of Thermal Protective Fabrics Designed To Protect Against Splash Hazards, Jeremy Osguthorpe

Theses and Dissertations

Thermal textiles used in Personal Protective Equipment (PPE) are used to protect individuals from the hazards of thermal energy. An analytical model of the diffusion of thermal energy within the fabric was developed to simulate the transfer of thermal energy due to a hot liquid splash. Based on the model results, it was determined that that the use of an orthotropic material in which the thermal conductivities in the radial and axial directions are different can be used to decrease the amount of heat transferred through the fabric and thereby increase amount of protection in PPE. An orthotropic material particularly …
