  • Title: [Absence of small-angle maximums on the x-ray images of ocular lens tissue].
    Author: Krivandin AV, Feĭgin LA.
    Journal: Biofizika; 1990; 35(3):461-3. PubMed ID: 2207188.
    Abstract:
    X-ray small-angle scattering study of bovine lens tissue was carried out. It was shown that X-ray patterns of lens cortical and nuclear native tissues did not contain the small-angle maxima. The maximum in the range of 15-20 nm Bragg distance appeared as a result of the lens tissue partial dehydration. Earlier such maximum was considered by some authors as the evidence of crystallin proteins short-range order in the native lens. Now it is confirmed to be a preparative artefact of dehydration. It was shown also that similar maximum in 15-20 range existed in the case of concentrated crystallin solutions. This indicates that supramolecular organization of crystallins in the native lens is not similar to that in the concentrated solution.
