Human breast cyst fluid (BCF) proteins were evaluated by sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE) after protein denaturation in the presence or absence of 2-mercaptoethanol. Both electrophoretic techniques yielded characteristic and reproducible banding patterns and achieved a high degree of resolution. The known four major protein bands were identified; silver-staining procedure resulted in more discrete bands (at least 13). Crossed-immunoelectrophoresis analyses of BCF allowed an improved protein mapping of this pathological fluid, presenting the opportunity of simultaneous quantification and identification of at least 22 proteins. The clinical and biological potential of these electrophoretic methods for detecting BCF proteins is discussed.

D011506	Proteins	Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.

D005348	Fibrocystic Breast Disease	A common and benign breast disease characterized by varying degree of fibrocystic changes in the breast tissue. There are three major patterns of morphological changes, including FIBROSIS, formation of CYSTS, and proliferation of glandular tissue (adenosis). The fibrocystic breast has a dense irregular, lumpy, bumpy consistency.
