February 9, 2017 >> Spent my Thursday morning labeling 40 microcentrifuge tubes for size exclusion chromatography (SEC). SEC involves running a protein sample through a column with microscopic porous beads that trap particles smaller than its pores while allowing larger particles to flow through and elute out first. The eluate is captured in small amounts at a time, separating the sample based on the size of the particles within it. This is one of many methods used for protein purification.
