Figure 1 . Renal function as measured by serum creatinine (serum CRE), whole body cyclosporine levels as measured by a monoclonal antibody assay (CyAlevels), and quantitative urine [kappa] light chain analyses (kappa) during the first 170 days posttransplant. Of note, is that between days +29 and +174, urinary [kappa] light chains were beneath the level of detection (<2.5 mg/100 ml), except for one value of 6.5 mg/100 ml on day +154.
