With about 29 known citations, the QuicKey Pro Rat Progesterone ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Rat Pg. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Rat Pg are added to the micro ELISA plate wells. Rat Pg in samples (or standards) competes with a fixed amount of Pg on the solid phase supporter for sites on the HRP linked detection antibody specific to Pg. 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 Rat Pg in the samples is then determined by comparing the OD of the samples to the standard curve.

Cute but no so comfortable
I previously owned a white sperry leather shoe that I bought from Marshall’s for about $35 & absolutely them, they were so comfortable , cute & great price.After running that pair down, I decided to buy another pair and found out the shoe was discontinued. The closest thing to what I had is this, the white crest vibe in leather. I was disappointed that this shoe was not as comfortable and didn’t fit quite the same. The back ankle part of the shoe caved into my skin and hurt. Sadly, I do not recommend this shoe for much walking. I hope Sperry decides to make this shoe more comfortable because it is cute.

Classics! Good material with no stretch.
Size: 28, Color: Verified Vintage
I am in love with these jeans. I ordered another pair in a different wash. I also sized up two sizes but I like the looser, slouchy fit.
