Dec 31, 2021 Steps of Sucrose gradient centrifugation. A sucrose density gradient is created by gently placing the sucrose with a lower concentration over the higher concentrations of sucrose in the centrifuge tube. The sample is placed on top of the gradient after which the tubes will be then placed inside an ultracentrifuge.

Equilibrium centrifugation. Typically, a sucrose density gradient is created by gently overlaying lower concentrations of sucrose on higher concentrations in a centrifuge tube. For example, a sucrose gradient may consist of layers extending from 70% sucrose to 20% sucrose in 10% increments (though this is highly variable depending on sample to be purified).

I used varying sucrose concentration gradients, depending on the requirement. For analysis of the aggregates, I used a 10-40% sucrose gradient with a 16hr spin - this puts most of the fractions above the Mr = 250,000 range. For I chain trimers and αβI complexes, I used 4-21% sucrose with a 15hr spin - this placed these complexes around the
