  • Application of polyacrylamide gel

    FAQ: Why are there extra bands visible on polyacrylamide gels? To provide increased intensity for the smaller bands and the reference bands, multiple fragments of the same size have been cloned into the plasmids used for many of the DNA ladders. These fragments, identical in size, are indistinguishable on agarose gels, but, on acrylamide …

This can preserve the gel forever (in theory). However, if you want to excise a band from the gel for digestion of other thing else, you need to wash the gel in H2O twice first.

  • How to store PAGE gel and keep the bands after

    2021-6-29 · The larger the gel, the higher the voltage. Once your proteins are on the resolving gel, you can increase the voltage. One rule of thumb is to set your voltage at about 5-15 V per centimeter of gel. Small gels will run closer to 100V, while large gels may approach 300V. Timing will vary for this step, ranging from 45 min to 2 hours.
