Description

QuicKey Pro Chicken Estradiol ELISA KitThe QuicKey Pro Chicken Estradiol ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Chicken E2.

Chicken 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

The QuicKey Pro Chicken Estradiol ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Chicken E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Chicken E2 are added to the micro ELISA plate wells. Chicken 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 ±2 nm. The concentration of Chicken E2 in the samples is then determined by comparing the OD of the samples to the standard curve.

Great toy for our mouthy chewing very active dog - he loves it and so do we!
Color: Fox-Crocodile
Great buy! Dog is very mouthy, so got this to try to focus chewing on a toy rather than me, and he loves it. Pockets are a little small for many treats, but they do hold very small ones tucked into each triangle - (16 small treats total between the two toys), and rolls up with a strong velcro which holds pretty well. Dog will forcefully wedge his nose into the roll trying to get to the treats and it doesn't unroll until he works it over. Wasn't positive how well it would hold up - he is a very mouthy puppy who is very strong and likes to shred, but out of all the toys, it has held up some of the best (on par with the kong toys so far) where others are not faring so well. He has pulled and tugged at the eyes, feet and ears repeatedly, and they are still firmly attached and no fraying on the treat spots at this time. He throws this thing around playing by himself and aside from being dirty now being one of his favorite toys, it looks as good as new. The only problem we have had is one of the squeakers no longer squeaks as he seems to have managed to remove that part of the noisemaker - but no holes, no rips, no shreds, nothing else showing wear and tear. He has even used it for tug of war on occasion and though we didn't let that last too long, it showed no signs of tearing or ripping from that either.

A favorite with my dogs but didn't last long
Color: Fox-Crocodile, Color: Fox-Crocodile
These have been a HUGE hit with my aggressive chewers but after less than 3 months, this is all that is left of the poor fox and alligator. My youngest STILL plays with them like they are brand new. I will probably buy them again but wish they were actually designed for aggressive chewers as advertised. I would say it's more for the average chewer. 4 stars because it was a good purchase and a top favorite toy but just didn't last long.

Too Cute!!!
Color: Fox-Crocodile, Color: Fox-Crocodile
This was a pleasant surprise and especially for the price!!! You get a 2 pack of toys!!!! They are absolutely adorable and made to last!!! Soft and lightweight!!! Has a nice squeakiness which my dog adores. I appreciate that they are made to fold up and Velcro so they become very compact. You can store them so easily and/or slide in your purse, traveling bag or leave one in your car. They fold up to be the size of folded socks. I recommend.

Our pup loves it (to pieces)!
Color: Fox-Crocodile
Fun toy for our playful pup, but nothing indestructible. She finds a seam and in days, the toy is in bits. Lucky for us, she still enjoys playing with parts! Package of 2. One down, one to go!
