Stress Biophysics: Time Resolution of Two Phosphorescences in Rat Tail Tendon.
Abstract
Phosphorescence of powdered monomeric polypeptide chains of collagen was induced by ultraviolet light at 277 nm. The emission was single-banded (half band width of approx- 30 nm) with a peak at 385 nm. Powered human glycoprotein, when excited at 277 nm, displayed a phosphorescent spectrum principally due to tryptophan residues (peaks at 413, 434 and 470 nm). The relative phosphorescent efficiency of glycoprotein was 4 times that of collagen. Washed tendon from rat tails, excited at 280 nm, and viewed at 425 nm, showed spectra suggesting the presence of two discrete excited triplet states functioning without interaction.
