Las proteínas anticongelante (AFP) se unen a planos específicos de hielo para prevenir o retardar el crecimiento del hielo. El análisis de afinidad de plano de hielo basado en fluorescencia (FIPA) es una modificación del método original de grabado en hielo para la determinación de planos de hielo unidos a AFP. Las AFP están etiquetadas fluorescentemente, incorporadas en cristales de hielo macroscópicos individuales y visualizadas bajo luz UV.
