Hi all,
In the context of the above going discussion can anybody post links for a
few relevant articles?
Thanks in advance,

We announce a call for synchrotron beam time applications in biological

Just one thing to add to that very detailed response from Ian.
We've tended to use a slightly different approach to determining a sensible
resolution cutoff, where we judge whether there's useful information in the
highest resolution data by whether it agrees with calculated structure factors

Rashmi,
I had a similar problem when I used an amicon to concentrate my protein, your
buffer composition indicates me that a lot of salt concentration and glicerol
makes your protein soluble, I had a similar buffer with a lot of saltt and 15%
glicerol, and I simply reason that my protein it is
For the history buffs and crystallographers needing some R&R and chill-out,
an interesting historic fiction read about the era of Newton and Leibnitz

Jacob, here's my (personal) take on this:
The data quality metrics that everyone uses clearly fall into 2
classes: 'consistency' metrics, i.e. Rmerge/meas/pim and CC(1/2) which
measure how well redundant observations agree, and signal/noise ratio
metrics, i.e. mean(I/sigma) and completeness, which
Another option I didn't mention is presoak your centricons in 30% glycerol over
night prior to usage.

Rashmi,
There are other membrane materials which might bind less. We have also found
that there seems to be binding sometimes to the plastic itself. So a
different manufacturer can help.
Also, always use same centricon for same protein. Sometimes you take a big
hit on a centricon's first
Hi Peter
You are right: the location of the prism experiment is most likely the
study at Woolsthorpe, e.g. see
http://www.isaacnewton.org.uk/texts/OfColours7 . Newton was admitted
to Trinity College in 1661 as a 'sizar' (a paid part-time student
employed by the College) but was forced to return t
