Abstract:
The rise of "-omics" related technologies makes it essential for students to have experience working with large bioinformatics data sets. Although”-omic” datasets are complex and abstract, effective instruction can be improved when students see the direct connections between the data on a computer screen and the results of "wet lab" experimentation. Here we describe the use of protein mass spectrometry as a means for students to gain experience in connecting bioinformatic data with work done at the lab bench. Course-based Research Experiences (CREs) based on these techniques are accessible to institutions of all types as a result of rapidly declining costs for whole genome and proteome analysis. Our implementation is within a CRE based on viral infection of a bacterial host; however, this basic paradigm may be applied to other experimental systems of interest.

FIGURE 3
SCAFFOLD Viewer output for a representative bacteriophage infection experiment using the bacteriophage Brusacoram. (A) Representative recovered peptide from the mass spectrometry reading. Yellow highlights indicate that LC-MS/MS detected peptide overlap with the gene product. Green highlights indicate modified amino acids. (B) In this case, a much smaller percentage of the predicted ORF was detected. Here, four peptides were detected that overlap with this ORF. A minimum of two detected peptides are required to confirm protein expression. ORF = open reading frame; LC-MS/MS = liquid chromatography-tandem mass spectrometry.
