| Abstract: | Analysis of the time decay of fluorescence anisotropy of 1-dimethylaminoaphthalene-5-sulfonyl (DNS) and fluorescamine derivatives of bovine alpha-lactalbumin and lysozyme reveals that no significant differences in mean rotational relaxation times are present. While fluorescamine molecules appear to orient randomly on these proteins, DNS is bound with a preferential orientation. Other fluorescence characteristics of the labels are also cited. |
