Uterine luminal proteins during the preimplantation period in the ferret.
The pattern of synthesis of uterine luminal proteins during the 6-day preimplantation period of the ferret has been analyzed by polyacrylamide gel electrophoresis and fluorography. The results demonstrate that several classes of protein, in particular those of molecular weights of 75,000, 58,000, 50,000, 18,000, and 8,000, are actively synthesized and appear in the uterine lumen during this period. Quantitative changes in the amount of radioactivity incorporated by specific proteins as viewed on autoradiograms are also suggested in association with the observed qualitative changes and both become more prevalent as implantation approaches.
