Yes, Gel Kit crates can be a pain in the . . . But! There's hope. Here are three guides, one for each crate. If items just aren't behaving, it's better to put them in a separate container (box, grocery bag) and bring them in that way. We would rather have them returned separate and intact, rather than together, smooshed and broken.
Here is a very cool time lapse video of gel electrophoresis in action, courtesy of retired SEP teacher and current RV explorer extraordinaire Aram Langhans.
Aram used the FlashGel System, created by Cambrex, and the actual running time was only 5 minutes. More info atwww.flashgel.com.
Gel electrophoresis is a commonly use tool for separating macromolecules (DNA, RNA, proteins) and their fragments based on size, shape, and charge. This kit allows students to use this technique to analyze the dyes used in sample loading buffers and DNA fragments.
A significant reduction in gel electrophoresis running time can be achieved by decreasing the concentration of the running buffer (TAE) and increasing the voltage:
BE SURE YOU:
If you exceed 20 minutes the gel will melt.
Under these conditions, the top edge of the gel (where the wells are located) may begin to melt a bit, but this should not impact the visualization of DNA fragments.

We recommend soaking the gel in 100 X Fast Blast for 3 minutes. Then rinse well (but carefully!) several times. It takes several rinses and some time to clear the background stain, but this process gives really great results. You can leave the gel destaining in a little water overnight and see really beautifully stained bands in the morning.
