Implication

Randomized trial examines binding and mitogenic effects of monoclonal antibodies in rat lymphoma cells, suggesting receptor dimerization is crucial for signaling.

Key Points

This research investigates the binding properties and mitogenic effects of specific monoclonal antibodies targeting prolactin receptors in rat lymphoma cells.
Examined binding affinity of antibodies T6, U5, and U6 in rat lymphoma cell lines (Nb2-11C and Nb2-SP).
Measured mitogenic effects of antibodies in vitro, comparing potency to human growth hormone (hGH).
Used immunoprecipitation and affinity labeling to identify binding sites and molecular weight of proteins involved.
Antibodies T6, U5, and U6 displayed mitogenic activity, with potencies significantly lower than hGH (185-, 70-, and 4700-fold respectively).
Anti-mouse IgG enhanced the mitogenic effect of all antibodies, reducing their potency gap but still showing 60-120-fold lower activity than hGH.
Des-13-hGH inhibited U5-induced proliferation noncompetitively, indicating ligand binding alters receptor conformation.
