Description

Mouse E3 (Estriol) ELISA KitThis 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

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.

The Ad got me, the reality didn't
Style: Variety Pack - Large (3-pack)
Directly from the ad- "Exclusive Noisemakers - Each large toy includes 3 high-quality round squeakers to deliver more sound to keep your best friend entertained.". Now my neighbor bought this squirrel with three high-quality squeakers nearly a year ago. It's ragged and tattered I just recently sewed it up for him where he chewed the one leg odd, but those three noise makers are still squeaking. Whe I got my pup, I immediately went to buy one and they were no longer selling them, so I've been on a search for one or an equivalent. These are not. There's no stuffing to get all over the place when your pup breaks into it, a plus. However the squeakers weren't particularly loud and were silenced in a few hours. Two were dead and the remaining one was very well on its way. The toy itself was pretty much intact but that had more to do with the lack of attention from the dog than how rugged the toy is. He'll pick it up once in a while but it certainly didn't meet my expectations. The good thing is that there are three of them so I can give him some brief excitement in the future. Wouldn't buy again.

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.
