FIG. 2.

2D electrophoresis pattern of serum (A), vaginal fluid (B), and vaginal epithelial cells (C). The positions of known proteins albumin (alb), transferrin (tf), immunoglobulin heavy chain (ighc), immunoglobulin light chain (iglc), cytokeratins (cks) and actin (act) were designated by comparison to master protein profiles in the Swiss 2D protein data bank from the Internet. In panel B, two proteins in vaginal fluid distinctly different from that observed in serum (panel A) are indicated by arrows.
