The effect of the protein content of diluents on peak height in rocket immunoelectrophoresis.
We have investigated the effect of different diluents in the quantitation of proteins by rocket immunoelectrophoresis. alpha2-Macroglobulin produced taller peaks as the protein content of the diluent fell to zero, and the dilution was increased. A maximum increase in height of 25-30% was recorded when saline was used as the diluent compared to a sample diluted in sheep serum. Albumin and transferrin showed similar, but less significant effects. Samples and standards should therefore contain approximately equal concentrations of protein for maximum accuracy.
