This product has been immuno-affinity purified and immuno cross-absorbed to reduce non-specific reactions.
The activity of each lot is determined using a dot-spot test system [Moeremans et al., J. Immunol., Methods 74, (1984), 353.]
This product is an immunogold reagent built around colloidal gold particles of 10nm. The particle population is monodisperse and thus shows minimal size variation and overlap. Typically, the coeffiecient of variance for the 6nm particle size conjugate is less than 10%.
