An automated flow immunosensor based on kinetic exclusion analysis for measurement of a free β-subunit of human chorionic gonadotropin in serum
Abstract
An automated immunosensor assay has been developed and validated for measurement of the β-subunit of human chorionic gonadotropin (β-hCG). The assay employed the flow kinetic-exclusion analytical technology of the KinExA™ 3200 instrument. Our KinExA™ consisted of a capillary flow observation cell with a microporous screen that maintained a compact
