Paper Abstract

The luminescence-kinetic technique of the monitoring of structural changes in albumins of human blood plasma that uses a luminescent probe-eosin is proposed. Phosphorescence of eosin bound to the globular proteins of blood plasma-albumins was recorded at room temperature. It is found that under the action of sodium dodecylsulfate on the albumins the rate constant of eosin phosphorescence decay grows and the intensity of eosin phosphorescence decreases. It is assumed that these changes are connected with the denaturing of blood plasma albumins by sodium dodecylsulfate.
