Provided is a method for controlling the degree of labeling (DOL) of a carrier molecule or solid support by the addition of a reactive label competitor to the labeling reaction. When the reactive label competitor is added to the labeling solution the competitor competes with the carrier molecule or solid support for the label, reducing the number of labels available to conjugates to the carrier molecule or solid support. This provides for a facile method that predictably alters the DOL of a carrier molecule or solid support.
