Optimization Of Separation And Detection Schemes For Dna With Pulsed Field Slab Gel And Capillary Electrophoresis , David Arthur Mcgregor Jan 1993

Optimization Of Separation And Detection Schemes For Dna With Pulsed Field Slab Gel And Capillary Electrophoresis , David Arthur Mcgregor

Retrospective Theses and Dissertations

The purpose of the Human Genome Project is outlined followed by a discussion of electrophoresis in both slab gels and capillaries and its application to deoxyribonucleic acid (DNA). Techniques used to modify electroosmotic flow in capillaries are also addressed. Several separation and detection schemes for DNA via gel and capillary electrophoresis are described. Emphasis is placed on the elucidation of DNA fragment size in real time as well as shortening separation times to approximate real time monitoring;First, the migration of DNA fragment bands through a slab gel can be monitored by UV absorption at 254 nm and imaged by ...


Isolation And Identification Of Root-Inhibiting Compounds From Corn Gluten Meal , Dianna Lan-Ying Liu Jan 1993

Isolation And Identification Of Root-Inhibiting Compounds From Corn Gluten Meal , Dianna Lan-Ying Liu

Retrospective Theses and Dissertations

Public awareness and concern for environmental protection and human safety has led to the search for naturally occurring compounds that are able to inhibit growth and development of weed plants. It has been reported that corn gluten meal is useful as a natural preemergence herbicide and fertilizer material for various plant production systems. The active components responsible for the herbicidal activity of corn gluten meal could potentially be used as natural herbicides;Based on the results from greenhouse and growth chamber bioassays using three species of grass plants, it was found that samples of hydrolyzed protein from corn gluten meal ...
