Calcium-binding proteins in the inner ear of Xenopus laevis (Daudin).

Kerschbaum HH , Hermann A .

???displayArticle.abstract???
Parvalbumin, S-100, calbindin-D28K and calmodulin-immunoreactive sensory hair cells were located in the inner ear of tadpoles and mature frogs of Xenopus laevis (Daudin). The relative number of immunoreactive cells varied in different compartments of the inner ear, depending on the Ca-binding protein studied.
