Abstract
Increasing the pH from 3.0 to 10.8 increased the uterine weight three-fold and the number of positive vaginal smears from 0 to 78 percent in immature rats injected with chorionic gonadotropin in aqueous solution. Activity of a solution held at pH 2.6 and 5°C for 24 hours was restored by neutralization.Keywords
