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 as described by Moeremans et al., J. Immunol. Methods, 74, (1984), 353.
This product is an immunogold reagent built around colloidal gold particles of 10nm. The paritcle population is monodisperse and thus shows minimal size variation and overlap. Typically, the coefficient of variance for the 6nm particle size conjugate is less than 10 %.
