Abstract Expression features of mouse parotid secretory protein (PSP) in postnatal development of parotid glands have been researched in mRNA level. The copies of PSP mRNA were 4.79E+06～1.32E+08, which were102 times higher than that of glyceraldehyde 3-phosphate dehydrogenase (GAPDH, 1.32E+04 copies) in different developmental stages. Messager RNA levels of PSP shifted with developmental stages: increased from birth to 3 weeks of postnatal, reached its peak at 3 weeks, then decreased; at last it kept at a even level at 12 weeks
