    Abstract:
    Antibodies against murine submandibular and sublingual mucins have been raised in rabbits. Both antisera appeared to be specific. Using these antibodies, the mucins were localized in the acinar cells of the submandibular and sublingual glands respectively. The dyed amylopectin method was used to estimate the activity of amylase in the salivary glands. The enzyme was localized either by a starch-substrate film method or with antibodies against purified parotid amylase. The activity of amylase in parotid homogenates is about 1000-fold higher than that in homogenates of either submandibular or sublingual glands, in which the activity was comparable. Amylase was localized in the acinar cells of the parotid gland with both localization techniques. In the sublingual gland, amylase was found predominantly in the stroma around the acini, and there was some evidence that amylase was present in the demilune cells as well. In the submandibular gland, contradictory results were obtained with both techniques. With the starch-substrate film method, amylase activity was found in the granular convoluted tubular cells, whereas immuno-reactive amylase could only be demonstrated in the acinar cells of this gland. It is concluded that in the submandibular gland amylase and mucin are present in the same cell type.
