Abstract: In situ observations of ice crystal growth in the supercooled solution of antifreeze glycoprotein(AFGP)labeled by the fluorescent molecule were carried out. Diffusion, adsorption, rejection and incorporation processes of AFGP molecules at/in front of the growing interface were clearly observed even at the very low concentrations. On the basis of the analysis of fluorescent intensity distribution, we found that the AFGP adsorption proceeded in two steps, namely from incomplete to complete adsorptions. Furthermore, the adsorption was reversible even under the complete adsorption state. We introduce the recent experimental results and the new adsorption model of AFGP molecules on ice interface.
