Periodic acid-Schiff (PAS) is a staining method that can be used to detect mucosubstances in tissues, see [1]. Mucin expression has been shown to correlate with tumor grade and type in salivary gland neoplasms, see [2][3][4], and can be detected using PAS staining, see [5].
This APP uses PAS staining for identification of mucosubstances in tissue sections from salivary glands. It automatically detects glandular regions of interest and differentiates between mucus and serous glands.
