Webb27 apr. 2024 · Yes most people have had problems with PAGE at some time as there are many areas where it can go wrong. Sometimes the plates are not sealed and can leak so the samples disappear sideways. WebbSpinning the clicked reaction removed the issue but also resulted at a lost of the protein. It sounds like he wasn't treating with a sufficient amount of DTT to break up the mixture. This unfortunately still doesn't differentiate between proteins stuck at the combs vs stuck at the stacking layer. sds-page experimental Share Improve this question

It's a guess, as I haven't run a algae sample on SDS-PAGE, but your migration problems might be due the algal polysaccharides that are present in your sample. Check if your protein purification protocol is specific for algal proteins and see if there is any step dealing with the algal polysaccharides. daikin applied productsWebb2 Answers Sorted by: 20 The reason for degassing your gels is to remove oxygen. Oxygen in the gel interferes with polymerisation, slowing it down and making it less consistent, so degassing makes it faster and more uniform.
