Nanodisc-based protein purification

Published 5 days ago • 1 min read

I came across a nanodisc-based purification approach that just changed how I think about membrane protein biochemistry.
​
I wish I had known about this during my PhD.
​
This approach, developed by Cube Biotech, allows the purification of membrane binding proteins without detergents.
​
It relies instead on a copolymer based nanodisc technology.
​
What makes this especially compelling is that the nanodiscs create an environment that closely resembles a native cell membrane.
​
Here is what stood out to me:
​
1)Compared to detergent based approaches, this nanodisc system produces proteins at higher purity and yield.
2)Protein homogeneity is significantly superior to what is typically achieved with detergent based methods.
3)Thermostability also appears to be better preserved in nanodisc purified proteins relative to detergent based purification.
​
You can go from cell lysate to pure protein in just two hours.
​
That kind of speed streamlines downstream applications such as cryo EM sample prep, enzyme activity assays, among others. Thus saving resources, time, and making the whole process more efficient.

Am I the only one who sees a huge disconnect between protein designs and how efficiently they can be executed in the wet-lab? What do you think it’s missing?What could be done for it be improved? Are the datasets used to train those models not good enough anymore?What do you think? Best, Omar. © ProteinReach|2026 SciLearningWorkshops LLC Unsubscribe · Preferences

Do you struggle with assessing the movement of specific residues of your protein during MDS? Here, I have a tool that can help you with that……It’s called eRMSF, and it allows you to assess the movement of residues during molecular dynamics simulation (MDS) runs at specific time points. So no need to rely on average values in a traditional RMSF plot, instead, you can complement that with eRMSF. You’ll be able to have a better sense of the types of domains, regions in your protein that are...

I just found a platform that lets you run Calvados force field simulations without touching a terminal.It's called FastFold, and it has a built in app for Calvados molecular dynamics simulations.Here's how simple it is:Go to FastFold, click on Apps, and open Calvados.You can input your own sequence of interest, or start with the examples section. There are several proteins to choose from, and I would recommend starting with lysozyme.Click on it and you'll be prompted to a settings page for...
