Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Mouse E3 are added to the micro ELISA plate wells.

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

Best toy I've found in a long time!
Color: Purple, Size: Medium (Pack of 1)
I got the small Nobbly for my 3lb puppy, but it's too big for her (she loves the xs bouncy ball one anyway). So my 15yo standard poodle adopted it and loves it. It's really too small for him so I watch him and don't leave him unattended. He is so old with bad teeth, and the softness of the center is great for him. It is totally cleaning his teeth, I see white where I haven't for years. But ZERO bleeding which is awesome. It's easy for him to hold and difficult for him to get to the rings, they last plenty long. I will order this one for him in a larger size, probably the medium. 100% satisfied with these toys! Ps I also have a hard chewing 12yo aussie that breaks teeth on anything like a bone. He gets thru the rings in minutes with the bouncy ball and nobbly, but takes way longer with the jack shaped one. He also likes to chew the purple ends of the jack, not just the rings. But I don't think they're hard enough to break his teeth. All of my dogs are different style chewers, but there is a good variety of designs so you can find the perfect one for your canine friend!

Dog-approved toy!
This dog toy was initially confusing because the instructions did not say or show where to find the power button and charging port. They were nowhere to be found until I realized I could unscrew the bottom part of the ball from the top (see picture). That revealed the button and port -- problem solved. Then on to the dog test. Our dog was initially confused by and ultimately fascinated with the ball as seen in the video. There are several operating modes depending on how active your dog is/wants to be. The toy seems quite rugged, so immune to rough dogplay, at least from a golden retriever. Our dog considers this a hit!
