Abstract:
Serum from patients with haemopoietic malignancies was tested for the presence of migration inhibition factor (MIF) and leucocyte inhibition factor (LIF) activity by standard assays. There was no correlation between the specific disease state and positivity of the sera for MIF or LIF activity. MIF activity in the serum of one patient with myeloma was present in the isolated IgG cryoglobulin fraction.
