Description

Bovine E3 (Estriol) ELISA KitThis Bovine E3 (Estriol) ELISA Kit uses the competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Bovine E3. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Bovine E3 are added to the micro ELISA plate wells. Bovine 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.

This Bovine E3 (Estriol) ELISA Kit uses the competitive ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Bovine E3. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Bovine E3 are added to the micro ELISA plate wells. Bovine 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 Bovine E3 in the samples is then determined by comparing the OD of the samples to the standard curve.

My dog like this!
Size: Small, Style: Mutts & Mongrels
My dog likes to play with this but I think she would like it better if the squeaker was larger.

He loves it new favorite
Size: Small, Style: Skit-Tails
Got this for my dog that's about 4.5 lbs and he has buckets of toys but this is his go to toy. It's so funny watching him play with it and I can tell you he is rough with it but still in perfect shape.

Don't buy it for your dog.
Size: Medium, Style: Sour Pooch
This was in the trash 10 minutes after it was opened. It is not durable. Better as a cat toy.

RainboW Latex Dog Toy
Color: Life's A Paw-Ty, Size: 4.75" H X 5.25" W X 2" D
The size was a good fit for my wire haired fox terrier, Gady. Quality: colorful, durable, Gady could grab it anywhere and shake it and make it squeak. Squeaking was her best joy. I recommend this Fringe Studio dog toy.

Cute but not durable
Color: Life's A Paw-Ty, Size: 4.75" H X 5.25" W X 2" D
Beautiful toy and super fun squeaker, my dog loved it so much, unfortunately, it didn't even last 30 minutes! My dog is not an aggressive chewer but the material is very fragile and she made a whole right away.
