Stilbene ELISA

Catalogue No. SJ2152 (Click Here to Order)

Overview

Key Advantages:

  • Detects glucuronide metabolite, reducing sample preparation time.
  • Direct Application of samples, no need for drying time.
  • Plates precoated with analyte specific antibody, reducing assay set up time.
  • Exceptional Limits of Detection across the various sample matrices

Diethylstilbestrol (DES), hexestrol and dienestrol (oestrogenic hormones) are collectively called stilbenes, which are banned worldwide for use in food producing animals. The stilbenes are growth promoting agents used in meat production. The use of anabolic agents has been banned within the European community since 1986, because of the potential risk to consumers from meat containing any residues . Stilbenes are also thought to be capable of initiating the carcinogenic process at small concentrations.
