    This product is a revolutionary new dual cytochemical labelling reagent. This probe is smaller than a whole IgG molecule, does not aggregate, and fluorescence quenching due to the gold particle is low. Normal methologies may be used successfully with this product. Due to some quenching of fluorescence by the gold particle, slightly higher concentrations of antibody are recommended for incubations. A blocking agent of 5% non-fat dried milk has been found to reduce background in some cases: this should be used before incubation with probe (in standard wash/blocking steps), and additionally, the Alexa Fluor®-ultra-small gold probe should be diluted in a solution also containing 5% non-fat dried milk before it is applied.
