Question (71965) | 17 beta Estradiol ELISA Kit (ab108667)

Go to datasheet (ab108667)

Question

Customer has kindly contacted us regarding the expected relationship between absorbance and concentration. When running the kit they found this relationship to be inverse (the highest concentration standard had lowest absorbance value). Is this to be expected with this product?

Answer

Our 17 Beta-Estradiol ELISA ab08667 is a competitive immunoassay. Therefore, one would expect an inverse relationship between the absorbance and concentration.
