Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Multiplexed single-cell in situ RNA analysis by reiterative hybridization

Currently, quantification of single cell RNA species in their natural contexts is restricted due to the little number of parallel analysis. Through this, we identify a method to increase the multiplexing capacity of RNA analysis for single cells in situ. Initially, RNA transcripts are found by using fluorescence in situ hybridization (FISH). Once imaging and data storage is completed, the fluorescence signal is detached through photobleaching. By doing so, the FISH is reinitiated to detect other RNA species residing in the same cell. After reiterative cycles of hybridization, imaging and photobleaching, the identities, positions and copy numbers of a huge amount of varied RNA species can be computed in individual cells in situ. Through this approach, we have evaluated seven different transcripts in single HeLa cells with five reiterative RNA FISH cycles. This method has the ability to detect over 100 varied RNA species in single cells in situ, which can be further applied in studies of systems biology, molecular diagnosis and targeted therapies.
