Soluble c-met is produced by some tumor cell lines.
Medium from A431 cells (lane 1), MCF-7 cells (lane 2), S180 cells (lane 3), BT474 cells (lane 4), and A549 cells (lane 5) was concentrated and immunoblotted using an antibody to the β chain of c-met. Only A431 and A549 cells produce soluble c-met.
