Preparing the Gel

Preparing the Gel

It is important to take your targets into consideration when selecting the gel type and percentage, as well as buffer composition when running and SDS-PAGE. This will help ensure that you have an even run of your samples, which will impact the accuracy and robustness of your data.

Equilibrating the Gel and Preparing for Transfer

Equilibrating the Gel and Preparing for Transfer

Gel equilibration is a critical step to help ensure an even transfer of your proteins from the gel to the membrane. It's also important to choose the right membrane for your targets. Paying close attention in these details will help increase the accuracy and robustness of your data downstream.
