Re: [ccp4bb] Suggestions to improve resolution of protein crystals

2021-03-22 Thread adarsh kumar
Dear Saurabh

I would like to share something that worked for me. I was in a similar
situation, though my crystals weren't as beautiful as yours are. I followed
Alexander McPherson's Crystallization of Biological Macromolecules and what
ultimately worked is as follows:
I did something called iterative seeding. That is, I took seeds from
generation 1 and grew generation 2, then took seed from generation 2 to
grow 3, and so on. It took me about 7-8 generations to get a crystal that
was diffracting in the 3 angstrom range. I tried more generations, but the
quality didn't really improve anymore. Afterward, I took these crystals and
tried to desiccate them before data collection. The method that best worked
for me was to dip it in a cryosolution with 5% glycerol --> keep it for 2
mins and then move to 10% glycerol and so on, up to 35% glycerol. You may
want to standardize the cryosolution as well. I was able to get up to 2.6
angstrom data at home source.

Hope this helps.

[ccp4bb] Post doc position available at Florida State University

2020-02-11 Thread Adarsh Kumar
Dear all

One postdoctoral position is available immediately in an enzymology laboratory 
to elucidate mechanisms of DNA/RNA synthesis, DNA lesion bypass, and base 
excision repair catalyzed by various human and viral DNA/RNA polymerases, and 
to mechanistically investigate gene editing enzymes including CRISPR/Cas9 and 
Cas13a. Background in structural biology (X-ray crystallography and/or CryoEM), 
biophysics, protein purification, and recombinant DNA techniques is preferred. 
An important criterion for selection will be the ability of the desired 
individual to pursue independent research in an active multi-disciplinary 
setting. Interested candidates should send a CV and a statement describing 
experience, goals, and reasons for the interest in this position, and arrange 
to have three letters of recommendation sent to Dr. Zucai Suo, Eminent 
Professor and Dorian and John Blackmon Chair of Biomedical Science, Department 
of Biomedical Sciences, College of Medicine, Florida State University, 
Tallahassee, FL. Dr. Suo can be contacted by email (zucai@med.fsu.edu).

Hi Jessica

You may try the following (if you haven't already):

1. Try solving it using P222 space group.
2. Re-index using different axes.

[ccp4bb] OT: Nvidia 3D vision 2 glasses with Ubuntu workstation

2018-12-20 Thread Adarsh Kumar
Hello everyone

We have just purchased a Dell workstation for crystallography data analysis. We 
were trying to use Nvidia 3D vision 2 glasses with it, but failed to do so. 
Please help me out with this one. Some relevant information is as follows:
OS: Ubuntu 16.04 LTS
Graphics : Quadro P4000 (unfortunately doesn't have a 3-pin DIN socket)
Monitor: Asus VG248QE

Thanks and regards

[ccp4bb] One postdoc position available at Florida State University

2018-11-06 Thread Adarsh Kumar
Dear all

One postdoctoral position is available immediately in an enzymology laboratory 
to elucidate mechanisms of DNA/RNA synthesis, DNA lesion bypass, and base 
excision repair catalyzed by various human and viral DNA/RNA polymerases, and 
to mechanistically investigate gene editing enzymes including CRISPR/Cas9 and 
Cas13a. Background in structural biology (X-ray crystallography and/or CryoEM), 
biophysics, protein purification, and recombinant DNA techniques is preferred. 
An important criterion for selection will be the ability of the desired 
individual to pursue independent research in an active multi-disciplinary 
setting. Interested candidates should send a CV and a statement describing 
experience, goals, and reasons for the interest in this position, and arrange 
to have three letters of recommendation sent to Dr. Zucai Suo, Eminent 
Professor and Dorian and John Blackmon Chair of Biomedical Science, Department 
of Biomedical Sciences, College of Medicine, Florida State University, 
Tallahassee, FL. Dr. Suo can be contacted by email (zucai@med.fsu.edu). 
Further information about the research projects in the Suo Lab can be obtained 
from https://med.fsu.edu/index.cfm?page=suolab.research.

Employer: Florida State University College of Medicine
Location: Tallahassee, Florida
Salary: NIH guidelines for post-doctoral salaries + benefits
Discipline: Life Sciences, Biochemistry, Biology, Biophysics, Structural 
Biology, and Biomedical Sciences

Re: [ccp4bb] on unit cell and asymmetric unit

2017-02-04 Thread adarsh kumar
Dear John

A unit cell can be produced by the symmetry operations on an asymmetric
unit. So, in your summary, if you just include number of copies in the
asymmetric unit along with the space group, it should do the job.
