Biochemical
Description
Estradiol is a steroid anabolic hormone, and used extensively for growth promotion in ruminants. With
obvious carcinogenicity, Europe and other countries have banned to use for food safety control. Estradiol
ELISA kits utilizing the latest biotechnology development has easy, rapid, and sensitive advantages.
This kit uses indirect-competition method mainly based on the immunological reaction between specific
antigen and antibody. Estradiol specific antigen coated on microtiter plates competes binding sites of
enzyme-labeled Estradiol specific antibody with added calibrator (or sample). With TMB chromogenic
substrate, the absorbance value was negatively correlated with residues of Estradiol. Under the
calibration curve, Estradiol content of the sample can be quantified multiplied by the corresponding
compare dilution.
Detectable samples
Estradiol residue can be quantitative of milk and milk powder.
