Dear all,
We have a postdoc position available at Washington University in St. Louis.
The postdoctoral research will focus on elucidating the structural mechanism of
membrane proteins as targets of cardiovascular therapy using novel
multidisciplinary approaches.
Please see attachment for full
I would like to know how to block activated groups on Thiol-activated Sepharose
4B (after coupling a peptide). The immobilized peptide will be used later to
purify/identify which antibody binds to this peptide.
For CNBr-activated sepharose I use Tris or ethanolamine to block the remaining
activ
Well - you are a long way from a solution!
All those rotation angles are close to each other..
What is the cell?
How similar is the model to your structure?
Have you looked at the self rotation function?

Hi Saif,
If your goal is to perform co-crystallization, I am completely agreed with
David's suggestions. Delta Tm does matter in the co-crystallization but
that's not always the case. I have some experience with protein complexes
where I successfully co-crystallized by using really high molar rat
Hello,
we had an interesting case in the lab many years ago... Using the
shift-assay, a student managed to identify conditions that markedly
stabilized the protein of interest. To cut a long story short, in the
end it turned out conditions were identified that gave monomers while
the biologic
Hi Saif,
Whilst in very general terms, ∆Tm does correlate with binding affinity (there
will of course always be exceptions to this rule), I don't think there is a
cutoff beyond which you know that co-crystallisation is feasible. The degree of
stabilisation will depend very much on the system yo
Hello everyone,
1) How much change in Tm (ΔTm) in a thermal shift assay is considered to be
significant ?
2) A negative ΔTm infers that the compound is making the protein unstable.
In such a case, will the co-crystallization be difficult or just impossible
or on the contrary it shouldn't matter
Dear colleagues,
We have an open postdoc position. 3 days left before deadline. Come joint us.
Great working environment, World-class science. Good work/life balance.
