Each lot of this antibody is quality control tested by ELISA assay. For ELISPOT applications, a concentration range of 2-6 μg/ml is recommended. For ELISA capture applications, a concentration range of 0.5-2.0 μg/ml is recommended. To obtain a linear standard curve, serial dilutions of IL-4 recombinant protein ranging from 250 to 2 pg/ml are recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.
