An ultrasensitive noncompetitive hybridization-ligation heterogeneous enzyme-linked immunosorbent assay was developed for the quantitation of antisense phosphorothioate oligodeoxynucleotides in plasma using a 96-well plate format. The principle of the assay is based on heterogeneous noncompetitive binding of the analyte to a template probe, followed by addition of signal probe via ligation and detection using a fluorescence microtiter plate reader. The result showed no significant interference noted from untreated human plasma. In addition, the method is selective for the specific sequence tested (ISIS 2302) and cross-reactivity toward the 3'-metabolites is minimal (< 0.22%). A linear range of 0.05 to 2 nM (r > 0.99) was obtained in human plasma for ISIS 2302. Intraday and interday accuracy for the method was found to be within 80-120% of actual value. Intraday and interday precision has a percentage coefficient of variation less than 20%. The lower limit of quantitation of the method was 0.05 nM (0.05 pmol/ml) with 100 microL plasma or an absolute amount of 5 fmol. In summary, the assay was demonstrated to be specific, accurate, precise, and sensitive for the quantitation of ISIS 2302 in human plasma and was applied to the analysis of plasma samples in pharmacokinetic studies.
