Use of protein A in a liposome-enhanced flow-injection immunoassay

Abstract

A flow-injection immunoassay for the herbicide alachlor has been developed in a sequential format using both a protein A matrix and liposomes. The protein A matrix is a commercially available controlled-pore glass that serves as the support for antibodies. The liposomes are tagged with a phospholipid–analyte conjugate and encapsulate a fluorescent dye that generates the signal. This report is the first demonstrated combination of these two technologies.
