Proteins in human uterine fluid.
The proteins in saline washings from uteri of women at different stages of the menstrual cycle were examined by polacrylamide gel electrophoresis at pH 4-5 and pH 8-9, isoelectric focusing in polyacrylamide, and immunoelectrophoresis. The components present were mainly serum proteins but small amounts of uterine-specific proteins were also detected. Measurement of the activities of several glycosidases in uterine washings revealed that alpha-L-fucosidase, beta-N-acetylgalactosaminidase and beta-N-acetylglucosaminidase were elevated when compared with serum.
