title: Radioimmunoassay for human aldolase A.
abstract: A radioimmunoassay was developed for the direct quantification of aldolase A in human serum. The method is a double antibody radioimmunoassay using radioiodinated aldolase A4 homopolymer as ligand, chicken antibodies to aldolase A, and rabbit antibodies to chicken IgG. The lowest measurable amount by this method was 2 ng (0.01 U). The radioimmunoassay was shown to be specific for the aldolase A subunit, with no cross-reactivity with human aldolase B subunits or homopolymeric human aldolase C (C4). The immunoreactive aldolase A in the sera of 41 normal healthy subjects ranged from 130 to 210 ng/ml (0.81-1.31 U/1), with a mean of 171 /+- 39 ng/ml.
