Description

QuicKey Pro Rat Estradiol ELISA KitWith about 45 known citations, the QuicKey Pro Rat Estradiol ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Rat E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Rat E2 are added to the micro ELISA plate wells. Rat E2 in samples (or standards) competes with a fixed amount of E2 on the solid phase supporter for sites on the HRP linked detection

With about 45 known citations, the QuicKey Pro Rat Estradiol ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Rat E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Rat E2 are added to the micro ELISA plate wells. Rat E2 in samples (or standards) competes with a fixed amount of E2 on the solid phase supporter for sites on the HRP linked detection antibody specific to E2. 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 Β±2 nm. The concentration of Rat E2 in the samples is then determined by comparing the OD of the samples to the standard curve.

Runs small
Size: 11 Wide Big Kid, Color: Black/White, Size: 11 Wide Big Kid, Color: Black/White
Runs extremely small, but does look like a nice shoe. I ordered 11W for my grandson. The image shows a different brand size 10 red shoe. As you can see the red one is bigger and wider than the new one ordered.

Good. Just good.
Overage at best. Not a bad sneaker for running and courts. The bottoms wore out faster than I thought but they are comfortable.

These are great shoes for walking. My son was able to walk around our trip to scotland and didn't complain about his feet hurting!

Sturdy, supportive, wish they were a bit more breathable
Bought these for my seven year old after he tore through a cheaper pair of tennis shoes in a month. These have held up very well, still looking decent after several months of heavy use, just a few minor scuffs. The fit is great and they are very comfortable for him. My only complaint is that they are not as breathable as I would expect and my son’s feet get hot and sweaty very easily inside. Overall, they’ve been very durable and I would buy again.
