Abstract

Antiserum was prepared to the proteins (amelogenins) isolated from fetal bovine enamel matrix. This antiserum was used to localize the amelogenins in the developing bovine molar by immunofluorescent microscopy. Amelogenins could be identified in the preameloblasts before enamel matrix deposition had begun as well as in the secretory ameloblasts. The closely adherent layer of stratum intermedium cells also contained some immunoreactive material, suggesting that they may contribute protein to the enamel matrix. The newly deposited enamel matrix consisted of brightly fluorescent particles. Mature enamel matrix did not contain the immunoreactive protein except in a thin layer along the dentino-enamel junction and adjacent to the ameloblasts. No other portion of the tooth bud or other tissues reacted with the specific antiserum.
