sequence information on that protein and an antibody) which ONE of the following methods will
you use?
A)Silver Staining
B) Coomassie Blue

Reverse-phase protein array
Proteome microarray
Lectin microarray Short Answer: Provide specific answers in your own words. 1. Describe the three main steps used when analyzing a molecule (protein) through Ion Mass Spectrometry
(10 pts)
2. You are a researcher working on human cancer. You have access to the following capabilities in your
laboratory; co-immunoprecipitation, FRET, Chromatin Immunoprecipitation, or Far Western Blot. Your
team believes a mutation in a hypothetical growth hormone (overdrive) is associated with ovarian
cancer. Pick any one of the available capabilities and develop an experiment designed to investigate if
the overdrive-cancer link is a plausible hypothesis. (20 pts)
