Fig. 5From: A Rapid Detection Method of Brucella with Quantum Dots and Magnetic Beads Conjugated with Different Polyclonal AntibodiesThe optimization of bio-probes. a QD probe, the fluorescence intensity of the complex was increased with the increase of the amount of IgY. The flu intensity reached the highest level and then stepped down. b MB probe, A280 nm of the IgG solution was determined before and after conjugation, and the amount of conjugated IgG of IMB was calculatedBack to article page
