title: Quantitative examinations of some rat proteins by means of absorbed anti-pregnancy and anti-feto sera.
abstract: This paper reports quantitative examinations of some rat serum proteins which occur only, or in rising concentrations in pregnant rats before and after birth. A new serum protein is described which is only demonstrable in female rats. In male rats this protein is found rarely and then in very small quantities.
