This Rat E3 (Estriol) ELISA Kit uses the competitive ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Rat E3. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Rat E3 are added to the micro ELISA plate wells. Rat E3 in samples (or standards) competes with a fixed amount of E3 on the solid phase supporter for sites on the HRP linked detection antibody specific to E3. Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450+/-2 nm. The concentration of Rat E3 in the samples is then determined by comparing the OD of the samples to the standard curve.

Great play and chew toy!
Pattern Name: Star
The dogs love these! They're sturdy and give them plenty of chew time. The size is great and they are very playable. The dogs have a lot of fun and the weight is just enough for our little dogs.

Great Dane Tested and Approved 5 Star
Pattern Name: Checkered, Pattern Name: Checkered
A picture is worth a thousand words applies to this product, as you will see in the attached photos these stand up to the abuse of a Great Dane. He has dragged me around the yard for hours already with this in his mouth and the stretchy handle keeps it shape. This ball is a little firmer than others of these I have had in the past, which helps exercise his giant jaw. I could get a few weeks out of the other brands I have bought. This brand is still like new well past the time others have failed. I will be ordering more as my French Mastiff is interested in one of his own (the boys do not like to share toys - most dog guardians understand).
