WebApr 19, 2014 · The loading buffer you add to your samples for gel electrophoresis has a few different purposes, but the exact amount does not really matter. The purpose of the loading buffer is to make the sample heavier so it is easy to get into the pocket and stays there to visualize how far the gel has run to denature the sample (only for denaturing gels) WebFeb 20, 2024 · Note: Loading buffer serves two purposes: 1) it provides a visible dye that helps with gel loading and allows you to gauge how far the DNA has migrated; 2) it contains a high percentage of glycerol that increases the density of your DNA sample causing it settle to the bottom of the gel well, instead of diffusing in the buffer. nerf stryfe rechargeable battery
