Diethylstilbestrol ELISA Diagnostic Kit

Diethylstilbestrol (DES) is effective anabolic steroids, coupled with estrogen activity. Poultry or fish in excess of diethylstilbestrol residues might cause harm to consumers. Diethylstilbestrol has been banned in food production applications. The EU demanded 2ppb-positive limit.

The Diethylstilbestrol 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.

Diethylstilbestrol specific antigen coated on microtiter plates competes binding sites of enzyme-labeled Diethylstilbestrol specific antibody with added calibrator (or sample). With TMB chromogenic substrate, the absorbance value was negatively correlated with residues of Diethylstilbestrol.

Under the calibration curve, Diethylstilbestrol content of the sample can be quantified multiplied by the corresponding compare dilution. Detectable samples Diethylstilbestrol residue can be quantitative of tissue and urine.

Specificity Diethylstilbestrol-----------------------------------------------100% Detection limit: 0.1ppb is the lowest detection limit of Diethylstilbestrol kit. Linear regression is between 0.1-2.7ppb.

Sensitivity: Tissue ----------------------------------------------------0.8ppb Liver ------------------------------------------------------1.5ppb Urine (Method 1)-----------------------------------------2ppb Urine (Method 2)-----------------------------------------1ppb Recovery rate: Tissue--------------------------------------------------75-105% Liver----------------------------------------------------75-105% Urine---------------------------------------------------75-105%
