Keratohyalin granules are storage sites for several different proteins in addition to profilaggrin, where they are sequestered from other cellular constituents until. The term keratohyalin was introduced by Waldeyer (cited by Matoltsy and Matoltsy ) for components of cytoplasmic granules of the mammalian epidermis. ABSTRACT. Keratohyalin granules were isolated in the native form from the epidermis of newborn rats by the use of citric acid and a detergent.
