Pl-CSA content was increased in the supernatants and lysates of cancer cells and in the plasma from mouse cancer models. (A) The cell lysates and cell culture supernatants from fifteen cell lines were collected and analysed using the double-antibody sandwich ELISA. The evaluated cell lines included six human cancer cell lines and four mouse cancer cell lines, as well as two normal human cell lines and two normal mouse cell lines as negative controls and the HTR8 cell line as a positive control. (B) The plasma concentration of pl-CSA was significantly higher in mouse cancer models than in control mice.
