I was part of a team researching treatments for eye diseases such as macular degeneration, glaucoma, and other eye related diseases. As a member of the Ocuscreen division I was responsible for helping to develop and validate a high throughput compound screen.

As a member of the Ocuscreen division I was responsible for helping to develop and validate a high throughput compound screen. The Ocuscreen method was able to detect compounds that were either protective or toxic to the retina. It involved the use of primary cells derived from bovine. My primary role was in the screening and analysis of the compound libraries for "hits." The main assay involved the use of bovine cultures exposed to various relevant stresses such as exposing primary cell cultures to high intensity blue light or oxidative type stress. Once the hits were discovered they were confirmed with a microscope using ICC Antibody staining. Another proprietary model involved the use of cell line exposed to a dual stress of a lipofuscion like compound called A2E aggravated with Blue Light. Protection was determined quickly using a fluorescent intercalating dye then confirmed with fluorescent antibody stains of ZO1 proteins. Compounds with similar molecular structures were purchased and tested head-to-head to compare activity. As a result Acucela was awarded two government grants for the Ocuscreen program. One grant from the EPA to develop the toxicity screen and another was awarded by National Institutes of Health as a screen for retinal protective compounds. Furthermore, I participated in Acucela's Visual Cycle Modulation program. In this case I cloned a cell-line enhancing them with the genes RPE65 and LRAT. These are key proteins that are critically involved in the visual light cycle. I performed the entire procedure from using PCR to copy the genes, analyzing their sequences for errors, ligating the genes into the vectors, producing copies by transforming competent e.coli cells, isolating and purifying the DNA, and finally transfecting the cell line with the genes of interest.
