Figure 1. Overview of the bead-based radioligand binding assay.

Figure 1.

The first step of the assay involves preparation of the antigen-coated magnetic beads. The second step allows the radioligand to bind with the target antigen on the beads. The final step isolates the beads from the supernatant and washes to quantify the target-binding fraction of the radioligand.
