Figure 2. Specificity of biosensor to detect rabbit IgG in rabbit serum (RS) and whole blood samples.

Figure 2

Receptor antibody (R) and target solution (T) were varied to determine specificity of linking chemistry. a, IgG detection in serum quantified with biotin/streptavidin linking chemistry, [IgG]=2.8 mg ml-1 per ELISA. (Standard deviations shown in plot were taken from 9 measurements) b, IgG detection in whole blood samples with biotin/streptavidin linking chemistry. Data normalized with blood samples from 2 different rabbits (tests on each rabbit were performed on 2 different sensors, each having 3 measurement positions) with IgG concentrations of 6.8 and 8.7 mg ml-1 per ELISA.
