The Rat CES1 (Carboxylesterase 1) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat CES1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat CES1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat CES1, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat CES1 in the samples is then determined by comparing the OD of the samples to the standard curve.

Long lasting play toy!
Color: Multicolor
Tuffy toys in general are great and they are a pretty good deal on Amazon. They are not indestructible, and if your dogs use them as chew toys they will eventually break through. My dogs have had this Armadillo since Christmas (and they do chew on it some) and the only thing missing is an ear. They like to play tug-of-war with it a lot. This is a bigger toy, but even my forty pound dog plays with it. I would not recommend this toy for dogs smaller than Border Collie size. You can make these Tuffy toys last longer if you don't allow your dogs to chew them--when your dogs starts chewing on non-chew toys trade them for a chew toy and when you catch your dog chewing on a chew-approved toy reward them for chewing. Eventually your dog will catch on and realize that if they want to chew there are certain toys that are allowed for that. In addition to being a great play toy this is a pretty cute toy too!

Not Tuff
Color: Black Yellow Phrog, Color: Black Yellow Phrog
Absolutely terrible and not “tuff” at all. My chocolate lab had this thing destroyed in less than two hours. I would not recommend these for the price.

Cute but Not Durable
Color: 2PK Green Leaping Phrog
⭐️⭐️⭐️⭐️ Cute but Not Durable Super cute toy—my dogs loved it right away! Unfortunately, they chewed the head off within a few hours. I ordered a second one because they were so into it, but the same thing happened again. I won’t be ordering a third, but they still play with their two headless frogs. So while it’s not the most durable, it definitely kept them entertained!

BUY IT!
Style: Baguette
This is AMAZING! My golden retriever loves it with hidden snacks on it or not. I wouldve put some more snack stacking on it, but dotn hesitate, BUY IT, its undestructible and fun.
