    Notizen: A light-scattering instrument capable of measurements on native DNA at angles as low as 10° is described. The major features of the instrument, which make it capable of low-angle measurements, are the use of an intense light source in which the incident beam is monitored directly and the use of a long, rectangular sample cell in which the scattered light can be measured at low angles with no interference from the incident beam. Methods for calibrating the instrument and for determining scattering correction factors are described. Procedures for the preparation and use of various calibration standards are given.

    Molecular weight of T7 and calf thymus DNA by low-angle light scattering (1968)
    New York : Wiley-Blackwell

    Notizen: A low-angle light-scattering instrument has been used to measure molecular weights of native calf-thymus and T7 DNA. Molecular weights obtained by extrapolation of angular data to 0° from measurements above 30° are less than molecular weights from extrapolation of data taken at low angles (below 30°). The low-angle molecular weights determined for calf-thymus DNA and for T7 DNA agree well with estimates of weight-average molecular weight obtained with other techniques. The low-angle light-scattering molecular weight for calf-thymus DNA is higher than previously reported values by light scattering at angles above 30°. A concentration dependence in the scattering from DNA solutions is also observed.
