متن کاملAtomic force microscopy applications in macromolecular crystallography.
Atomic force microscopy (AFM) can be applied both in situ and ex situ to study the growth of crystals from solution. The method is particularly useful for investigating the crystallization of proteins, nucleic acids and viruses because it can be carried out in the mother liquor and in a non-perturbing fashion. Interactions and transformations between various growth mechanisms can be directly vi...
متن کاملSub-atomic resolution X-ray crystallography and neutron crystallography: promise, challenges and potential
The International Year of Crystallography saw the number of macromolecular structures deposited in the Protein Data Bank cross the 100000 mark, with more than 90000 of these provided by X-ray crystallography. The number of X-ray structures determined to sub-atomic resolution (i.e. ≤1 Å) has passed 600 and this is likely to continue to grow rapidly with diffraction-limited synchrotron radiation ...

be hypothesised that adaptation to pollinators has been a driving force behind the diversification of some of the major elements of the southern African flora, " Johnson writes. Southern African flowers are known to be attractive to a range of species from long-probscid flies, oil-bees, hawkmoths, butterflies, birds and rodents. Many of these pollination interactions have been characterised in ...
متن کاملCigarette secrets.
-Evidence is presented that microscopic tumours (of a transplantable murine mammary carcinoma, M8013X) grow faster than larger, palpable, tumours. Microscopic tumours are also more radiosensitive than larger tumours. The decrease in radiosensitivity in larger tumours is prevented to a large extent by misonidazole, which has no significant effect on the radiosensitivity of microscopic tumours. T...
