ELISA inhibition curves for TCSG using A) Reagent concentrations: antiserum 2621, 1:8,000 (final dilution in wells); coating antigen TCSG-BSA, 4 µg/mL (100 µL/well), secondary Ab – GAR- HRP, 1:10,000 dilution. Coefficient values: Amax 0.88, Amin 0.44, IC50 510.9, slope 0.31 B) 5-BSA as the coating antigen: Heterologous format; reagent concentration: antiserum 2621, 1:5,000 (final dilution in wells); coating antigen - 1 g/mL (100 µL/well), secondary Ab – 1:5,000 dilution. Coefficient values: Amax 0.82, Amin 0.07, IC50 2.85, slope 1.18. Standards prepared in 10% MeOH-PBS (5% MeOH-PBS as final concentration in wells). Each data point represents the mean of quadruplicates.
