Detailed Information on Previous Workshops, Seminars and Courses
- Nebraska Center for Biotechnology - Summer Proteomics Workshop, July 15-16, 2019. Participants gathered to experience the full proteomics analysis pathway from sample preparation and sample running to data analysis and interpreting a final report. They were given steps for approriate preparation techniques and were shown how to best interpret reports and results. There were also hands on opportunities for those who were interested.
Anne showing participants how different protein concentrations result in different stain saturation on gels.
Anne shows participants the steps in digesting and extracing proteins from gel bands.
Participants practicing gel protein digestion and extraction techniques.
Felicia shows participants how to set up a Solid Phase Extraction (SPE) to clean protein samples.
A close up of the apparatus used for SPE.
Participants preparing to work with the SPE apparatus.
Mike showing the participants how samples are run on the Thermo Q-Exactive-HF mass spectrometer.
