Pipetting & eGels In this week’s lab, we were tasked with familiarizing ourselves with standard pipetting equipment. We utilized P20, P200, and P2000 micropipettes, along with petri dishes and glass slides. Having prior experience in a wet lab, it was fun to explore the equipment artistically. I started by creating some “droplet art” on a glass slide using colored water. I then decided to make a smiley face and a DNA strand in the same fashion, pipetting individual droplets of colored water and “streaking” them to create lines.
Lab: DNA Gel Art Today in lab, we attempted to make DNA Gel Art using restriction enzymes and software (Benchling). In recitation, we were given an example of someone using time-controlled gel work to create an image, so I came up with a plan to use that framework to create an image of Pac-Man. I used SalI, which cuts only a single 500 bp strand from lambda DNA, for my digest to create my “blocks” that I would effectively “stack” as I pipetted them at interval times on the gel.
This week in lab, we used the Opentrons machine, giving us a taste of lab automation with an artistic twist. We pipetted flourescent, genetically engineered E.coli onto agar mixed with activated charcoal to create our design and canvas respectively. After a 16 hour incubation period, we were able to see images of our results under UV light! I decided to make two designs, one of the US Virgin Islands to pay homage to where I’m from, and the other was the Dark Side of the Moon Album Cover, as I thought it used a good variety of colors. The robot moved from top left to bottom right, which prompted a discussion with Ronan about the most optimal pathing system for the trajectory. The robot’s movement is controlled by a Python script, and Ronan created a website to generate the coordinates of each colored pixel, which the script implemented.
