ELISA results of purified Polyclonal Donkey Anti-Sheep IgG Antibody Alkaline Phosphatase Conjugated tested against Sheep IgG. Each well was coated in duplicate with 1.0microg of antigen. The starting dilution of antibody was 5microg/ml and the X-axis represents the Log10 of a 3-fold dilution. This titration is a 4-parameter curve fit where the IC50 is defined as the titer of the antibody. Assay performed using Buffer (p/n NPP-B500) and Substrate (p/n NPP-10).
