[ccp4bb] postdoc position in Singapore
A postdoctoral position is available at the Laboratory of Virus Structure and Function in the Duke-NUS Graduate Medical School, Singapore. The Laboratory of Shee-Mei Lok (http://www.duke-nus.edu.sg/web/research_faculty_sheemei.htm) is looking for a post-doctoral fellow to work on the structural studies of dengue viruses and its complexes. Her laboratory uses a combination of techniques such as x-ray crystallography and cryo-electron microscopy (CryoEM) including single particle analysis and cryotomography. Facilities such as in-house x-ray machines and cryoelectron microscope (Titan Krios, FEI) are available in the National University of Singapore. The post-doctoral fellow will mainly participate in the computational side of structure solving and should preferentially have prior experience in solving either cryoEM or x-ray structures. Training in crystallography or cryoEM data collection and image processing however, will also be available if necessary. Interested individuals are invited to send cover letter, cv and a list of referees to Dr Shee-Mei Lok by email (sheemei@duke-nus.edu.sg).

Re: [ccp4bb] Singapore Research, facts and comments?
Dear all, I work in Duke-NUS in Singapore. Overall the funding climate in Singapore is very good compared to most places in the world and the research quality has improved significantly to a world class standard in the past 10 years. Duke-NUS, NUS and NTU are Universities and we are used to writing grants to support all our research, like most Universities in the world. The complains by people working in A-star agency is because, they did not use to need to apply for any money. But now the government decides that it is time to wean people off the the easy money and compete for grant.

Are you talking about electrophoresis? As far as I know it does not work for the mass. The velocity of a protein depends on the charge at a particular pH, the mass and shape of molecules etc. It's very difficult to take all these things into consideration. Otherwise this would be a very convenient method, much easier than the analytical centrifugation or gel-filtration that are usually used. However, electrophoresis does not work for mass determination. Besides, complex formation hugely depends on the protein concentration. If you dilute your mixture, your complexes might dissociate. There is equilibrium constant between different types of complexes.

MWCharge MW/Charge A 22 -5-4308 B 17-24 -702 This experiment is partly to determine stoichiometry, but also to determine roughly the strength of the interaction. B definitely runs much faster than A alone, as predicted, but I am wondering what to expect with various oligomers. Should ABB run faster or slower than AB? What about AABB? Theoretically, AA should certainly run slower than A, and BB slower than B, simply because the mass/charge ratio is the same, but the overall mass is greater. But what happens when you have AAB, for example? There must be an equation relating the mass/charge and mass (and perhaps gel percentage) to the speed traveled in the gel--but what is the equation?
