For immunoassays, the capture sandwich format is commonly used for xMAP® protein assays, where the analyte is “sandwiched” between a capture and detection antibody. The capture sandwich format is compatible with a wide variety of target analytes.

A competitive format is used when the target analyte has a low molecular weight and only one or two antibody-binding epitopes or if only one antibody is available. Competitive xMAP® assays can be developed using either antibody-coupled or antigen-coupled beads and can be multiplexed with the capture sandwich format in the same assay.

An indirect format is used for serological assays to measure the amount of antigen-specific antibody present in biological samples. Once a format has been chosen, the beads can be coupled to the proteins used in the assay.

Nucleic Acid Assays

The open architecture of xMAP® Technology enables numerous nucleic acid assay applications. Multiplex nucleic acid assays are developed by coupling user-defined sequence-specific capture oligos to MagPlex® beads or using MagPlex®-TAG™ beads that are already coupled to unique 24-base DNA sequences (anti-TAGs).
