Antibody microarrays using resonance light-scattering particles for detection.
Antibody microarray measurements show great potential for the simultaneous quantification of many proteins in small amounts of body fluids and extracts. Over the last few years, a micro-array platform centered around the concept of microarrays in microtiter wells was developed, and for the best assays we have achieved lower limits of detection in the femtomolar range using resonance light-scattering particles for the staining of biotinylated detection antibodies. Although conceptually simple, these multiplexed sandwich assays are technically challenging. Here we describe in detail our protocols and procedures for the manufacturing of antibody microarrays with up to 48 different antibodies and for performing plasma measurements.
