Description

Human CPE (Carboxypeptidase E) ELISA KitThe Human CPE (Carboxypeptidase E) 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 Human CPE. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human CPE and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate

The Human CPE (Carboxypeptidase E) 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 Human CPE. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human CPE 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 Human CPE, 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 Human CPE. You can calculate the concentration of Human CPE in the samples by comparing the OD of the samples to the standard curve.

Didn’t hold up for more than a minute but the silicone strawberry by itself is durable.
Pattern Name: Strawberry, Pattern Name: Strawberry
Our best dog toy reviewer, a cattle dog mix, gave this toy a big thumbs up ONLY because she could demolish it in seconds. Not minutes, but seconds. The toy has a pouch stuffed into a silicone toy strawberry. The pouch is really stuffed in well, so much so that I couldn’t remove it, but she sure did! In about a minute all that was left was the dismembered strawberry “leaves” and a silicone strawberry which, oddly enough, she seems to enjoy. The silicone strawberry seems quite durable by itself. The toy is brightly colored and small in size. This not a durable toy unless you have a dog that is not an aggressive chewer, but for us, it is not recommended.

Good for larger treats, not small ones
Pattern Name: Carrot, Pattern Name: Carrot
Our dog loves this treat toy. It has been very durable as far as the rubber part goes but the cloth carrot insert not so much, that got torn apart pretty quickly. Also this works for bigger treats, but once the cloth carrot was destroyed, there was no way to keep small treats from just falling out. Now we use it to stick larger chew sticks in the holes and it works to help her keep it in place while chewing.

Dogs love these treat toys
Pattern Name: Strawberry, Pattern Name: Strawberry
I have big dogs who live for treats and love to play puzzle games to find treats. You can stuff these toys with small treats which gives your dog a mental challenge while working to figure out how to get them out. The quality of these toys are great but durability with big dogs will be short lived. The strawberry green top immediately was de-stuffed while dog was looking for more hidden treats. The corn husk seems to be more challenging for them to get the treats out. However my smarter dog was determined and eventually reaped the rewards. I would recommend these toys for dogs who will not rip them apart.... but really is there any pup who doesn't enjoy de-stuffing a stuffie squeek toy?

Great feeder for high energy puppy!
Size: Large, Color: Blue
I have a 50lb high energy puppy. She is not a fast eater, BUT she loves this activity and it gives me about 30 minutes of uninterrupted bliss. It took about 10 minutes to demonstrate to help her get the hang of it. She will sit, spin the barrel with her paw, then sniff every divider, only open the ones with her food, and then restart the process. It is sturdy and stays on the floor as she paws and pushes. It might move a little, but not far. This is my favorite puzzle toy by far and I love that it is "hard" enough to keep her occupied but not enough that she gets frustrated and doesn't want to do it.
