Their activities are distinguished as five isozymes (1, 2, 3, 4 and 5) according to electro-mobility on disk gel electrophoresis. In this study we determined the AcP activity on the root surface tissue of 11 extracted human premolars (subjects 12-17 years old) as a standard activity of the AcP in the healthy root surface condition. The average activity (nmol/min/mg) of 11 teeth was determined to be 23.6±9.3 (mean±SD), and the activity was reduced to 18.2±7.5 by the addition of lOmM L-tartrate. Therefore 77% of the total activity represented tartrate resistant AcP activity. On polyacrylamid gel electrophoresis, isozyme bands of 1, 3 and 5, compared to leucocyte isozyme pattern, were demonstrated as the general pattern of AcP activity on the root surface of human tooth. The color development of the active bands, 1 and 3 were reduced by the addition of L-tartrate, while 5 was not reduced and identified as tartrate resistant AcP.}, pages = {54--59}, title = {ヒト歯根表層組織中の酸性ホスファターゼアイソザイムについて}, volume = {18}, year = {1992} }
