Week 9-DNA Gel Electrophoresis

This week has been super busy! Among cardiomyocyte isolations, western blots, protein assays, operations on our live specimen, and a potluck party thrown in honor of my graduate student mentor's successful research proposal, I had the opportunity to perform my very own DNA Gel Electrophoresis. Electrophoresis is a method used in this lab for genotyping among our six different experimental groups. Specifically, it is used to determine whether our gene of interest is available in a particular sample after PCR has been performed.  It involves four steps: 1) preparing the gel; 2) loading the gel; 3) running the gel; and, 4) visualizing. With the lovely help of my multi-talented research team, I created a video of me performing these steps.
