Learn More About This Simulation
This short, targeted simulation is adapted from the full-length Parkinson’s Disease simulation.
How to purify the protein sample to obtain a high purity compound? Now you have the opportunity to learn one of the techniques that can do that! In the Ion Exchange Chromatography simulation, you will learn what chromatography is and you will perform your own purification experiment.
Prepare the protein sample
First step in chromatography is the preparation of the sample. Therefore, in the beginning you will extract monomers of alpha synuclein (aSN), a protein that is involved in the development of Parkinson’s disease. In order to do so, you will use sonication to extract the protein, which is produced by an E. coli bacterial strain.
Perform ion-exchange chromatography
Next step is the purification of the extracted aSN monomers by ion exchange chromatography. First, you will learn about the different parts of the chromatography equipment to get familiar with them and then you will apply your knowledge and run the experiment yourself!
Analyze the results and pick the right fraction
Finally, you will analyze the chromatogram and find the fraction that has our purified aSN protein. Your work will help the researchers in their further study. Maybe your contribution will help us find a cure for Parkinon’s disease?

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."

Labster can be integrated within a school's LMS (Learning Management System), and students can access it like any other assignment in their LMS. If your Institution does not choose an LMS integration, students will log in to Labster's Course Manager once they have an account created. Your institution will decide the access method during the sales process.
Labster is only available for purchase by faculty and administration at academic institutions. To procure Labster, simply reach out to us on our website. Schedule a demo, book a meeting to discuss pricing, start a free trial, or simply fill out our contact form.
Labster simulations are created by real scientists and designed with unparalleled interactivity. Unlike point and click competitors, Labster simulations immerse students and encourage mastery through active learning.
Labster supports a wide range of courses at the high school and university level across fields in biology, chemistry and physics. Some simulations mimic lab procedures with high fidelity to train foundational skills, while others are meant to bring theory to life through interactive scenarios.
