TLDR
The SAXS profile in the rapid cooling process showed that the loose double helical structure was constructed within 150 s, but the CD signal slowly changed with around 2 days to recover the native tight double helix.About:

TL;DR: In this paper, it was shown that the abscissa of the intersecting point of the 1/v2 and 1 /v branches, when extrapolated to the transition region, is connected in a characteristic way with the statistical chain element or the length of persistance, which represent two different measures for the stiffness of the chain molecule.

A universal calibration for gel permeation chromatography
TL;DR: In this paper, the relationship between elution volume and molecular weight has been investigated, and it has been shown that the relationship depends on the contour length of the molecular chain rather than the radius of gyration of the polymer molecules.
