ASSAY DEVICES COMPRISING A POLY(ACID) MEMBRANE, AND METHODS USING THE SAME

摘要

Assay devices that include a poly(acid) membrane are provided. Aspects of the devices include a solid support and a poly(acid) membrane on a surface of the support, where the poly(acid) membrane includes an affinity element. In using the assay devices, a sample is contacted with the poly(acid) membrane and then a signal is obtained from the membrane. Also provided are kits that find use in practicing the methods described herein. The compositions and methods described herein find use in a variety of different applications, including analyte detection applications.
