Notizen: [Auszug] IT has long been recognized that some of the halos observed on X-ray photographs of liquids and amorphous substances may be spurious and due to the white radiation peak. Some of the observed reflections obtained from concentrated solutions of tobacco mosaic virus1 were under ...

Notizen: [Auszug] THE purpose of the vector map described by Fankuchen and Riley1 to which Dr. Wrinch has taken exception in her recent letter2 was merely to show that the cyclol C2 skeleton does not contribute anything to the specific character of the observed X-ray ...

Notizen: [Auszug] WE have examined by X-ray methods crystals of the protein material prepared by F. C. Bawden and N. W. Pirie1 from tomato plants suffering from bushy stunt disease. The crystals were in the form of isotropic rhombic dodecahedra of average diameter of only 0.01 mm. Consequently, no ...

Notizen: [Auszug] We have recently been fortunate in obtaining well-developed crystals of two proteins-chymo-trypsin and haemoglobin. The former were prepared for us by Dr. Northrop of Princeton and the latter -methaemoglobin of horse--by Dr. Adair at the Physiological Laboratories, Cambridge. In both cases the ...

Notizen: [Auszug] In order to determine the structure of protein crystals from X-ray diffraction effects it is usually necessary to measure fairly large single crystals. An exception to this rule is the case of crystals belonging to the cubic system, for which powder photographs should provide sufficient data. A ...

Notizen: [Auszug] FURTHER work on preparations of proteins from virus-infected plants tends to confirm and extend the conclusions expressed in our previous letter1. We had there shown that both concentrated solutions of these proteins and the material prepared from them by drying gave orientated ...
