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.

Well designed, well built.
Size: 25in
The stick facilitates powerful, long distance throws. The ball makes a light whistling noise (to help your dog track the ball) through the air, flys far, and has held up well. I live in an area with mountain lions, and they often hunt at night, so I haven’t taken advantage of the glow-in-the-dark feature.

Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

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.

Nice set of balls
Size: Medium
The squeaker quickly became my dog’s favorite ball and has replaced the fuzzy tennis balls. My dog is a nonstop fetcher and these chuck it balls are durable and fun.
