Dear all,
We have two funded postdoctoral positions available to investigate
mitochondrial gene expression and genome-segregation mechanisms primarily using
cryo-EM but also biochemistry and macromolecular crystallography (MX). We are
located in the newly-built Biomedicum on the northern campu
Hi Tom,
For acidic side-chains, these kind of interactions are described by Maria
Flocco and Sherry Mowbray in:
"Strange bedfellows: interactions between acidic side-chains in proteins." J.
Mol. Biol. (1995) 254, 96-105.
Best regards,
Martin

Raji, we use the 50 ml Cornings up to 25K RCF in our F13S-14x50cy rotor without

Hi,
With the electronic Biohit 8 channel pipette you can set up 3x96 drops in 5
minutes. Lowest volume is 0.2 ul. We have used this system for a couple of
years with RNase free filter tips for RNA-protein complexes. With the recent
arrival of a shared Mosquito we have used the Biohit less but it
Dear Phil,
Is the twin fraction varying? Can you correlate the variation of twin fraction
with variations in crystal morphology or handling?
With constant perfect twinning you could try MIR using the phase determination
method of Yates & Rees (Acta Cryst. (1987). A43, 30-36). I can't access the
Dear Anita,
Sometimes the protein of interest has a relatively strong inherent binding
affinity to the IMAC
column. Have you tried to bind the cleavage reaction to an IMAC column
and then elute using a shallow imidazole gradient?
In fact, Porath developed IMAC chromatography as a tool for prote
Hi,
I'll second Israels's comment. Since the yield per coupling in synthesis is
lower for RNA than for DNA it gets really expensive over 30-35 nucleotides.
However, you can stitch together several 30 nt oligos using either T4 RNA
ligase or T4 DNA ligase (with a DNA splint).
