Dear all,
I need to decide between buying an AKTA prime and an AKTA FPLC from GE health
care. I understand AKTA prime is a low-pressure system, but because it is too
much cheaper than AKTA FPLC, it is still very attractive to me.
I will mainly use it for Nickel columns and gel filtration colum
Dear all,
Thanks a lot for all the feedbacks on AKTA prime. They are so helpful that I
have abandoned the idea of buying one. Now it is a choice between AKTA FPLC and
Bio-rad DuoFlow. I heard that DuoFlow is not as robust as AKTA and that its
parts break down often. The question is whether qua

Dear all,
Thanks for the almost 100 replies I have received. I appreciate every one of
them very much. Since some asked for a summary, here it is, albeit with more
questions. :-)

Hi,
I apologize if this has been posted here before, but I will need to buy a
standard stereo microscope for viewing crystals. Could anyone give me some
suggestions regarding the brand, model, and retailer? Thanks in advance!

Hi,
In a new structure we observed a hydrogen bond between an aspartate side chain
and a main chain carbonyl group. Because both of them are electronegative, I am
puzzled.
My questions are: does this hydrogen bond make sense at all? any precedent for
such a hydrogen bond?
I would appreciate
Dear all,
Thanks for all of your replies. The crystallizatin pH is 5.5, above pKa of
aspartate, which is 3.8. In addition, the protein functions at neutral pH, and
this aspartate is part of the active site. So it doesn't appear that the
aspartate is protonated due to low crystallization pH or
Dear all,
I am looking for examples of different crystal packing at different
crystallization temperatures. I would appreciate it if anyone could provide the
name of the crystallized protein or, even better, the reference of the
crystallization experiment.
Thanks,
Frank
