Author Information
Author(s): C. O'Sullivan, M.R. Price, R.W. Baldwin
Primary Institution: Cancer Research Campaign Laboratories, University of Nottingham
Hypothesis
The study investigates the purification and characterization of polymorphic epithelial mucin (PEM) from the sera of advanced breast cancer patients.
Conclusion
The study successfully isolated and partially characterized PEM, which is elevated in the circulation of advanced breast cancer patients.
Supporting Evidence
- PEM is elevated in the circulation of advanced breast carcinoma patients.
- The purification process involved immunoaffinity and size-exclusion chromatography.
- SDS-PAGE and immunoblotting confirmed the characteristics of the isolated PEM.
Takeaway
Doctors found a special substance in the blood of women with advanced breast cancer that could help them understand the disease better.
Methodology
The study used immunoaffinity and size-exclusion chromatography to purify PEM from patient sera, followed by SDS-PAGE and immunoblotting for characterization.
