Description

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

Strong, mighty and reusable.
Package Size Name: Triple, Size: 141 Sheets (Pack of 2)
I love these specifically for our RV because they work great to take my makeup off at the end of day as well. These really are different and more durable then most others on the market. Can even be rinsed and reused before discarded if need be.

Close to a cloth
Package Size Name: Triple, Size: 141 Sheets (Pack of 16)
Hi All, These are simply terrific paper towels that are close to grabbing a cloth. They come in triple size rolls which we find helpful. I get the ones that can tear at a half size sheet, and find the roll last longer when you don't have to use a full sheet for everything. For paper, these are softer than most, and don't have that sandpaper feeling like so many do. I think you'll like them. Prices and sizes change depending on the stock available so watch for the right price for the right rolls you prefer.

Balls

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.
