In the following SDS-PAGE and native gel of the same samples, which lane contains two proteins that are the same molecular weight, but do not interact?

Mass spectrometry sequencing requires

You can search for proteins that bind DNA using all of the following EXCEPT

Which of the following is the best technique used for lysing cells?

Below is an SDS-PAGE (A) of an induced lysate (Lane 2) and a western blot (B) using an anti-target protein antibody. The protein was purified via affinity chromatography (Lanes 4-6). What is the molecular weight of the major contaminant (not the target protein) that was removed by the purification?

Heat shock proteins were discovered by comparing protein expression levels in cells at different temperatures using

What conclusions could you draw from this peak from a size exclusion column?

A protein was run on both an SDS-PAGE and native gel, as shown below, with the addition of a drug (+) that disrupts protein structure. Which of the following is TRUE?

Which of the following can be used to determine a protein’s molecular weight, or to detect protein interactions with metals by analyzing weight differences in the holo vs. apo state?

Which would be the best choice for studying protein-protein interactions or protein modifications?
