Sounds odd as cross-linked resins should not exhibit such behaviour. I
have seen this with e.g. phosphocellulose columns. The charged groups on
the matrix repel each other at low ionic strength and expand hence the
increased bed volume with water etc. At high ionic strength the charges
are shield
Yes, CM-Sephadex expands and contracts incredibly. For other than batch methods
you will be much better using CM-Sepharose. I guess it is cross-linked
sepharose, and doesn't swell up much even in distilled water.
What is happening is the negative charges of the carboxy groups repel each other,
Hello All
I am using CM Sephadex C50 column for my protein. I equilibrated column with
MOPS buffer pH 6.0. But during elution I am using only NaCl2. This looks like
changing the bed height. Before starting elution the bed height was around
60cm. After starting elution the bed height decreased a

Presumably it counts all missing reflections in the refinement procedure.
Seems wrong!
What software are you using?

Do an mtzdump to the resolution you used - that gives you a count of
observed reflections, plus the possible number of reflections..

Hi
A new Postdoc position is available in my group at Imperial College
(South Kensington campus) in London, UK, from April 1st 2017 on. The
position will be highly suitable for somebody with experience in
membrane protein structural biology. A particular advantage would also
be experience in m
Dear All
when i deposit my structure, it show the "Number of unique reflections
measured(40854)"
but the "Number of Unique reflections refined against(48369)".
how could that happen?
I'd appreciate for any suggestion about this.
