Table 1. Fluorescence intensity in the test zone of an immunochromatographic test strip at different combinations of antibodies against human IgE.

	Antibodies immobilized in the test zone
	Clone 4F4	Clone ME-113
Antibodies conjugated to QDs	Fluorescence intensity, relative units
Clone 4F4	1.3	2.1
Clone ME-113	4.8	0.6

The QDs-conjugates of the same clones of antibodies were used at a concentration of 0.8 µmol/L (QD concentration).

A standard solution of IgE with a concentration of 200 kU/L was used as a sample.
