The overall objective of the Proteomics Shared Service (PSS) is to provide The University of Arizona Cancer Center investigators with a dedicated facility and expertise in analyzing proteins for their identity, quantity and function via state-of-the art modern mass spectrometry and peripheral analytical instrumentation.
Over the past funding cycle, the PSS has performed proteomics analyses for Cancer Center members belonging to 5 different programs (units of service).
We offer a variety of proteomics services and tools to members of the Cancer Center.
- Gel Electrophoresis - used to separate proteins in a gel matrix
- 1D SDS-PAGE on 7 and 11 cm formats
- separation by MW
- coomassie, silver and Sypro Ruby images
- 1D SDS-PAGE on 7 and 11 cm formats
- 2D SDS-PAGE on 7 and 11 cm formats
- separation by pI and MW
- coomassie, silver and Sypro Ruby images
- Differential In-Gel Electrophoresis (DIGE) - expression analysis of complex protein samples
- Cy3, Cy5 and Cy2 labelling
