ASU Electronic Theses and Dissertations

This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

In vitro selection technologies allow for the identification of novel biomolecules endowed with desired functions. Successful selection methodologies share the same fundamental requirements. First, they must establish a strong link between the enzymatic function being selected (phenotype) and the genetic information responsible for the function (genotype). Second, they must enable partitioning of active from inactive variants, often capturing only a small number of positive hits from a large population of variants. These principles have been applied to the selection of natural, modified, and even unnatural nucleic acids, peptides, and proteins. The ability to select for and characterize new functional molecules …

Infertility has become an increasing problem in developed countries and in many cases can be attributed to compromised sperm quality. Assessment of male fertility typically utilizes semen analysis which mainly examines sperm morphology, however many males whose sperm appear normal are sub- or infertile, suggesting that sperm from these males may be deficient in a protein or suite of proteins. To date, very little is known about the composition of sperm or the complex maturation process that confers motility and fertilization competency to sperm. Chapter 1 discusses the use of whole cell mass spectrometry to identify 1247 proteins comprising the …
