Question: How do #transcription factors activate transcription?
Outside the DNA binding domain of a TF, there are numerous disordered domains, including activation domains that interact with co-activators--
very little known about that
activation domains are disordered, poorly conserved, and binding to co-activators is very low affinity

Biochip Device Tests Malaria Drug Efficacy, Safety
A lab-on-a-chip device with human organ cells is shown in lab tests to distinguish between malaria strains and detect drug toxicity when assessing blood for seven days.

Do you know those annoying layer lines on #3Dprinted parts? In resin #3Dprinters, they are as small as 25 microns… And we can make #microfluidics molds with these printers. Does this mean we can reach 25 microns features in Z?
YES! We can make a mold for a “staircase” microfluidic device. Now we have steps of 25um on the height of the channel. This #microfluidic does not only filter #microparticles, but also size-sort them. Particles of different sizes will be blocked on different steps.

This week, Diya Fathima started in our research group. Diya has a B.Sc. degree in #Biotechnology and is working on biosensors. She will work in our project #KEAnI. We are developing systems for rapid #antibiogram generation in #nosocomal #infections. The main topics are development of the #microfluidic chip, establishment of staining protocols for the detection of bacteria in the microfluidic chip and chip-based purification of the blood sample (i.e., separation of blood cells).

In a #microfluidic flow cell #pseudomonas were grown on glass and exposed to an #antibiotic gradient (~0.1-9.9x MIC) via 1-channel of a dual inlet. Cells moved towards the abx in a pilG-dependent manner and died. #pyocin expression was observed and this is thought to be a competitive behaviour.

Yesterday Danny Ferreira Dias presented his #BSc work on a #microfluidic pumping set-up.
He worked with MF pumps and valves from #Labsmith. Unfortunately, the company’s documentation is rather poor and for the programming a #ReverseEngineering had to be done, i.e. to analyze the commands on the oscilloscope and to translate them into a bit sequence ( 🤔).
Nevertheless, in the end it was possible to control the set-up by a GUI running on a #RasPi. Congratulations for the nice work, Danny!
