Assay Protocol

Abstract In this solid-phase competitive enzymoimmunoassay for albumin in human urine, antiserum to human serum albumin labeled with horseradish peroxidase (EC 1.11.1.7) is incubated with solid-phase-bound human serum albumin in the presence of sample or standard. Results obtained correlate well (r = 0.96) with those of an established fluoroimmunoassay. The present assay covers the range 0.9 to 200 mg/L and can be performed within 1 h. These characteristics, together with the simplicity of the assay protocol, make it very useful for monitoring low concentrations of albumin in urine. Detection of such minimal albuminuria allows initiation of therapy that may prevent development of clinical proteinuria and associated diabetic nephropathy.

Strategic peptide sequences, patterned on the sequence 136–148 of the primary structure of human serum albumin, have been immobilized on a cross-linked polyacrylamide support using the solid phase peptide synthesis technique. Certain of the resulting materials proved to be efficient adsorbents for bilirubin from aqueous phosphate buffer solution. Amino acids such as lysine and arginine favour the binding of the ligand, whereas glutamic acid reduces it markedly. From Scatchard plots, first and second equilibrium binding constants, in the range of (0.3–9.6) × 104 M−1, were obtained using a site treatment. These binding constants are comparable to that for the binding of bilirubin by a larger fragment of bovine serum albumin that contains the synthesized sequence.
