1. A method for assaying mammalian cells to determine if tumor cells are present, comprising:
a. providing a sample of medium surrounding said mammalian cells, and
b. detecting the presence of a 120-130 kD fragment of α-dystroglycan in the medium, whereby the presence of the fragment indicates
that tumor cells are present.
