Abstract
A method for calibrating a flow cytometer or fluorescence microscope and for quantitating binding proteins, such as antibodies. Populations of microbeads are provided which are in equilibrium with a saturating amount of fluorescently-labeled protein. The microbeads may have an incorporated fluorescent dye which has a strong signal in a selected channel of a flow cytometer, but no signal in other channels.
