Background: The Gyrolab™ workstation benefits from fully automated transfer of reagents and samples originating from a storage microplate onto a compact disc containing solid-phase microstructures composed of a 15 nl streptavidin-derivitized bead bed.
Results: This paper describes the development, full validation and use of the method in a regulated environment to measure a humanized bispecific monoclonal antibody-domain antibody (GSK-A) molecule using the Gyrolab immunoassay system in cynomolgus nonhuman primate plasma ranging from 5 to 250 µg/ml. The method was subsequently used in support of the TK portion of a regulated preclinical study in monkeys.
Background: The cardioprotective effects of glucagon-like peptide-1 (GLP-1) and analogs have been previously reported. We tested the hypothesis that albiglutide, a novel long half-life analog of GLP-1, may protect the heart against I/R injury by increasing carbohydrate utilization and improving cardiac energetic efficiency.
Methods/principal Findings: Sprague-Dawley rats were treated with albiglutide and subjected to 30 min myocardial ischemia followed by 24 h reperfusion.
Background: Domain antibodies (dAbs; ∼10-15 kDa) are made up of the variable heavy chain or the variable light chain of the antibody structure, and retain binding capability. dAbs have proved difficult to detect in plasma using immunoassay without specific antibodies raised against the dAb.
Results: A sensitive and selective UPLC-MS/MS method for the absolute quantification of a dAb in monkey plasma was developed (range: 1 to 500 ng/ml) without the need for a specific capture antibody.
