[ccp4bb] One protein, two data sets

2019-09-08 Thread Prerana G.
Dear all, We have two data sets of a protein with the following parameters: 1. Space group P212121 a=61.0, b=100.34, c=133.23 No. of molecules in ASU - 2 2. Space group P212121 a=58.33, b=62.86, c=109.45 No. of molecules in ASU - 1 Can we use them as two different structures? Regards, Prerana #

[ccp4bb] Poor resolution

2015-04-11 Thread Prerana G.
Dear all, I am working on a 40kDa protein. The size and diffraction pattern of the protein crystal seems to be fine but I am getting poor resolution (3.0 Å). How can I increase the resolution? Regards, Prerana

Hi Vicky, I tried to change the ratio of paraffin:silicon oil to 1:2, but still the protein precipitated. So I tried to do it other way round, I kept paraffin:silicon oil ratio as 2:1 and so far it has not precipitated. Apart from that, I separately used the two oils.In silicon oil there was immed

Hi, Sorry for asking an off-topic question, I have recently purified a protein having a molecular weight of 40kDa and concentration of the protein was 8mg/ml. When I tried to set the protein for crystallisation using micobatch method, the protein started precipitating in most of the buffer conditi
