As FIDA relies on changes in hydrodynamics radius, it works best for small targets such as motifs from IDPs.

Luckily, this is what we intended to use it for 😉

Medium throughput protein expression and purification for protein design using heat lysis This protocols describes medium throughput protein expression in E. coli using heat-lysis as a built in purification step. It is intended for preparation of heat-stable de novo...

Crucial to the screening is the lab scale protein expression pipeline below.

We use an old trick beloved by the IDR-community for protein purication: Heat lysis.

Due the thermostability of the binders, we get ~95% pure lysate after a heating step in 96-well plates.

Screening de novo designed protein binders in unpurified lysate using flow induced dispersion analysis Computational protein design can create binders against targets of interest, but identifying binders with sufficient affinity still requires biochemical screening of many designs. In this work, we te....

Experimental verification is increasingly the bottleneck in protein design projects.

In this paper, we develop a new mini-binder screening pipeline based on the microfluidic sizing technique called flow-induced dispersion analysis (FIDA).

The technique works best for small targets with a large change in radius of hydration upon binding – e.g. SLiMs in IDPs 😊 – but also works for larger proteins with only a 10% change in RH upon binding.

We find that it works excellently with “boiling lysis” – exploiting the high thermostability of binder designs to remove endogenous proteins – and then simply dilution the supernatant with buffer before measurement.

FIDA measure radius of hydration based on diffusion in a microfluidic capillary.

This allows us to pick out successful binders based on the increase in R_H – a one-point measurement for initial screening and titration for affinity determination.

How do we screen do novo designed binders most efficiently? In this pre-print, we show that the microfluidic sizing technique FIDA allows us to pick successful binders in a single measurement using minimal sample:

Trigger warning: FOMO

How often do you go to a conference where you are excited about EVERY SINGLE TALK! Well, I guess it helps if you get to make the program. 😀

Probably the best conference venue in Denmark?

Tomorrow, we kick-off our condensate meeting in the Carlsberg Academy ⬇️.

Thank you to the Novo Nordisk Foundation for the grant to host our dream meeting, and to the Carlsberg Foundation for hosting us at this beautiful site.

We have a new review/perspective on the potential of biomolecular condensates in microbial cell factories. The emphasis is on the trade-offs that have to be navigated when designing such synthetic organelles.

Dear American friends.

We agree that status quo in the Artcic is not an option.

So let’s talk about how we can fix it - together.

The bulk of the prize comes in the form of a grant for educational development.

We plan to use this to integrate computational skills - mainly python and R - across the whole curriculum. The prize allows us to hire someone the spearhead this across all the courses in our department!

This is part of a new series of teaching prizes spanning from primary school to university level by the Novo Nordisk Foundation.

Seen from the outside, it looks like a 💰-push to increase the public and institutional recognition of teaching. Interesting to see how this will evlve.

Authoritarianism runs strong in this family. It is an utter disgrace.

The world order has changed. The US is no longer the leader of the free world.

The key question going forward: Who is?

Which side of history do our politicians choose - and who will lead?
