Abstract: | Summary Acid phosphatase, generally thought of as a lysosomal enzyme and indeed widely employed as a lysosomal marker, has been found associated with the Golgi complex of all cell types from the crop, intestine and digestive gland ofArion ater. Reaction product was also detected within the multivesicular bodies and cytoplasm of columnar cells from the crop and the multivesicular bodies of mucous cells from the intestine. A vacuolar localization was obtained in the digestive cells of the intestine and digestive gland. Secretory protein granules in the calcium cells of the same gland and apical vacuoles in the so-called thin cells also showed a positive reaction.This work was undertaken as part of a slug research project under the direction and co-ordination of Dr. D. K.Roach, supported by A.R.C. Assistance was given by Mr. T. R.Mainwaring in the preparation of tissue for electron microscopy.I would like to thank Professor J.Brough and Professor D.Bellamy for providing facilities and encouragement. |
