Pregnancy-associated murine protein-1 (PAMP-1) in wild rodents.
The presence of pregnancy-associated murine protein-1 (PAMP-1) in a number of wild rodent species was examined using tandem crossed immunoelectrophoresis and anti PAMP-1 antisera raised in rabbits. PAMP-1 is a protein present in female laboratory mice and rats; analogues were readily detected in the following species: Musculus domesticus, M. musculus, Apodemus sylvaticus, A. agrarius, A. flavicollis, and Microtus arvalus. Immunologically, cross-reacting proteins could not be detected in the laboratory hamster and laboratory guinea pig. Maternal PAMP-1 serum levels were recorded throughout pregnancy in the two species of house mouse: M. domesticus and M. musculus. Both proteins exhibited maximum concentration at day 11 of gestation. During early pregnancy, M. domesticus females had significantly higher serum levels than those of M. musculus females.
