TI  - Measurement of urine albumin levels with a monoclonal antibody based in-house ELISA
AB  - Microalbuminuria is considered to be an early indicator of diabetic nephropathy. We have previously reported the establishment of A-HAlb/98 hybridoma secreting monoclonal antibody that specifically recognizes human serum albumin (HSA). In this report, an in-house enzyme-linked immunosorbent assay (ELISA) was developed using this antibody for the measurement of urinary albumin (UA) and UA was examined in 24 different samples. A-HAlb/98 was used as the capture antibody by immobilizing onto microtitre plates in ELISA format. HSA-specific polyclonal rabbit immunoglobulin was labelled with biotin and then used as the tracer antibody. The dynamic assay range of ELISA for albumin was established to be 10-1000 ng/ml, and the albumin levels determined by ELISA were well correlated (r = 0.8831) with those obtained by the liquid-phase immunoprecipitation method (The Orion Diagnostica TURBOX® U-albumin assay). The ability of this in-house ELISA to quantitate UA in nanogram ranges makes it a favourable candidate for utilization in diagnostic applications as well as in research studies.
