N2 - The application of SPR for the measurement of concentration of human serum albumin (HSA) in urine was studied using the compact integrated SPR sensing system Spreeta. HSA was immobilized via cystamine and glutaraldehyde onto the gold sensing area and a competitive assay for HSA was developed using limited amount of the monoclonal antibody AL-01 in solution. Measurements were carried out in the flow-through mode and the interaction between immobilized HSA and antibody was observed in real time. To obtain reproducible results, different conditions of the measurement (method of immobilization of HSA, data evaluation, concentration of antibody, regeneration procedure) were tested. The calibration curve for clinically relevant concentrations of HSA in urine samples was constructed using 300-times diluted antibody in the form of ascites fluid. The measuring range was between 0.1 and 5 mg/l of HSA, the sensing surface was successfully regenerated and suitable for more than 20 assays. The developed method was tested on real samples of urine; to overcome the non-specific adsorption of urine components, the differential approach was adopted and the measured signal was corrected by subtraction of the response observed in the absence of the antibody.
