Abstract
We present the establishment of a sensitive immunoassay for the determination of α1-acid glycoprotein (orosomucoid, AGP) in rat serum. The assay is based upon antigen capture by surface-immobilized specific polyclonal rabbit anti-AGP antibodies with biotinylated rat AGP (rAGP) as the tracer, and formatted as competitive enzyme immunoassay. Signaling is performed by streptavidin-conjugated horseradish peroxidase. Enzyme activity is quantified by an enhanced chemiluminometric method, allowing the sensitive detection of rAGP serum levels in small sample volumes.
