SOLUTION: monoclonal antibodies

PROBLEM:  The status of the TRAIL receptors ( assessed by immunoblotting and flow cytometry ) could not predict TRAIL sensitivity of MM cells .

SOLUTION: TRAIL receptors

PROBLEM:  Using a whole cell competitive binding assay , normal human lymphocytes had 5977 + / - 1487 ( mean + / - SD ) binding sites / cell and a dissociation constant of 10 + / - 2 nM .

SOLUTION:
