Le proteine antigelo (AFP) si legano a specifici piani di ghiaccio per prevenire o rallentare la crescita del ghiaccio. L'analisi FIPA (Ice Plane Affinity) basata sulla fluorescenza è una modifica del metodo originale di incisione del ghiaccio per la determinazione dei piani di ghiaccio legati all'AFP. Gli ARP sono etichettati fluorescentmente, incorporati in cristalli di ghiaccio singoli macroscopici e visualizzati sotto la luce UV.
