A low-angle light-scattering instrument has been used to measure molecular weights of native calf-thymus and TT 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"

## Abstract Lowβangle light scattering results reported previously demonstrated that measurements on high molecular weight native DNA must be made at angles below 30Β° in order to obtain correct molecular weights. Earlier lightβscattering data obtained on denaturated DNA at angles above 30Β° showed n
The conformational properties of -carrageenan in 0.2M LiI and -carrageenan in 0.2M LiCl were analyzed by size exclusion chromatography combined with low-angle laser light scattering. Fractionated samples with narrow molecular weight distributions (M w /M n Ο³ 1.4) were used, and M w in the disordered
