The Rabbit DKK4 (Dickkopf Related Protein 4) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rabbit DKK4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rabbit DKK4 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rabbit DKK4, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. 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 nm ± 2 nm. The OD value is proportional to the concentration of Rabbit DKK4. You can calculate the concentration of Rabbit DKK4 in the samples by comparing the OD of the samples to the standard curve.

The Best!
Color: Croissant
Out of all the stuffable, freezable dog treat toys I’ve tried over many years with several dogs, this one is #1! So easy to clean and freezing the little goodie cup that you insert in to the toy is so much easier than trying to stuff a small hole! The extra little grooves on the outside I fill with no sugar no salt peanut butter and my pup loves it! This is a heavier toy, so not sure how a small dog would do picking it up or carrying it around, but our 45 lb guy has no problem! Seems like it is very durable and just might last forever!

Bump on tongue
Color: Croissant, Color: Croissant
It’s a good idea but should be made with hard rubber and the back should not be able to come off. It gives off shards of plastic and gave my dog bumps on his tongue. I do love the idea and it keep my dog busy in the morning while I had my first cup of coffee and before everyone woke up.

She loves it
Color: Octopus
My dog loves this. I mixed plain yogurt and blueberries and froze the two cups. She went to town and it kept her busy for about 15 min. It’s easy to open compared to some of the other toys like this. Easy to clean too.
