About This Simulation
Perform the chromatin immunoprecipitation with exonuclease treatment (ChIP-exo) protocol, and prepare the target DNA to learn how E. coli survive in acid stress conditions.
Learning Objectives
- Understand the use of exonuclease treatment in ChIP-exo technique.
- Understand the key steps for performing the ChIP-exo technique as well as the importance of each reagent:
- Adding formaldehyde to the culture to fix the bonds between proteins and DNA.
- Lysing the cells using lysozyme and sonication.
- Addition of specific antibodies.
- Use of magnetic beads.
- On-bead enzymatic modifications.
- Off-bead enzymatic modifications.
- Understand the molecular mechanism of ChIP-exo.

Learn More About This Simulation
In the ChIP-exo simulation, you will perform the chromatin immunoprecipitation with exonuclease treatment (ChIP-exo) protocol in order to get a DNA sequence to elucidate the acid stress mechanism of Escherichia coli. You will learn how to fix the protein-DNA interactions and lyse the cells using a sonicator, add magnetic beads to the sample, and perform different on-bead and off-bead enzymatic modifications. From this, you will learn how the exonucleases work.
Will you be able to prepare the target DNA to understand how E. coli survive in acid stress conditions?
For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

A Labster virtual lab is an interactive, multimedia assignment that students access right from their computers. Many Labster virtual labs prepare students for success in college by introducing foundational knowledge using multimedia visualizations that make it easier to understand complex concepts. Other Labster virtual labs prepare learners for careers in STEM labs by giving them realistic practice on lab techniques and procedures.
Labster’s virtual lab simulations are created by scientists and designed to maximize engagement and interactivity. Unlike watching a video or reading a textbook, Labster virtual labs are interactive. To make progress, students must think critically and solve a real-world problem. We believe that learning by doing makes STEM stick.
Yes, Labster is compatible with all major LMS (Learning Management Systems) including Blackboard, Canvas, D2L, Moodle, and many others. Students can access Labster like any other assignment. If your institution does not choose an LMS integration, students will log into Labster’s Course Manager once they have an account created. Your institution will decide which is the best access method.
Labster is available for purchase by instructors, faculty, and administrators at education institutions. Purchasing our starter package, Labster Explorer, can be done using a credit card if you are located in the USA, Canada, or Mexico. If you are outside of North America or are choosing a higher plan, please speak with a Labster sales representative. Compare plans.
Labster supports a wide range of STEM courses at the high school, college, and university level across fields in biology, chemistry, physics, and health sciences. You can identify topics for your courses by searching our Content Catalog.
