Estradiol ELISA Diagnostic Kit

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.

Specificity Estradiol -------------------------------------------------100% Detection limit: 0.5ppb is the lowest detection limit of Estradiol kit. Linear regression is between 0.5-40.5ppb.

Sensitivity: Milk ---------------------------------------------------------4ppb Milk powder ----------------------------------------------4ppb Recovery rate: Milk ---------------------------------------------------60-100% Milk powder ----------------------------------------60-100%
