Absorption of Water and Nuclear Lens Protein by Nuclear Lens Tissue

Abstract

Intrinsic water and soluble protein were removed from insoluble nuclear lens tissues of bigeye tuna, yellowfin tuna, and squid. These lens tissues were then used to absorb water and protein from extracts of nuclear tissue from these species. The quantity and type of absorption between the tunas were similar; between the tunas and squid, dissimilar. This indicates that nuclear lens tissue can be used to demonstrate both close and distant phylogenetic relationships.
