Background

The kit employs homogeneous time-resolved fluorescence (TR-FRET) technology for the detection of His-tagged proteins. It can be used to confirm whether the His-tag motif of a protein is recognizable by anti-His antibodies or to estimate the concentration of His-tagged proteins.

As illustrated, the His-tagged protein is labeled with an Acceptor (Ac-Protein His Tag), while the anti-His antibody is labeled with Europium (Eu-anti-His). Upon binding of the antibody to the His-tag on the protein, the proximity between the donor and acceptor enables fluorescence resonance energy transfer (FRET), resulting in a specific 665 nm emission signal from the acceptor. In the presence of other His-tagged proteins, they compete with Ac-Protein His Tag for binding to Eu-anti-His, thereby reducing FRET signal generation. Higher concentrations of competing His-tagged proteins lead to stronger competition and lower signals. The signal intensity is proportional to the binding between Ac-Protein His Tag and Eu-anti-His, with no washing steps required.

Aggressive chewer puppy approved
Color: Cinamutt Roll - Large, Size: Large
My aggressive chewer puppy loves this. It is pretty sturdy. He hasn't destroyed it yet and he's had it for over 3 months now.

Pretty hard to clean
Color: Cinamutt Roll - Large, Size: Large
We've had this for about a week now. I have 2 dogs, one small one about 55lb. I bought this for my big girl, but lil man is determined to get the best of this toy. Usually they don't both go after the same toys, so this is interesting. The trouble is, neither one of them can get all the treats out if something makes it all the way down into the crevice. It's surprisingly deep. The up side is that they'll try for quite a while before giving up. The down side is even if you put it in the top rack of the dishwasher, something stuck deep in there isn't going anywhere until you dig it out yourself. I tried a plastic knife but it broke the second time I used it in there. I wound up using the metal handle of a reusable straw cleaner. Which then I had to wash that, too. Then it needs to dry overnight before it can be used again. All in all, the dogs like it fine, it's gross to scrape out and wash, takes longer than most toys to dry, and I have the feeling that will eventually cause me to pass it to someone else's dog long before my two have gotten tired of it. At this point I'm pulling out of the toy rotation for a week or two because I'm not ready to clean it a third time.

Hyena Proof
Color: Acorn - Large, Size: Large
I have an American Bulldog that would chew a brick if he didn’t have an alternative lying around. They won’t last forever (nothing does) but we’ve had two of these over the course of a year and for him that is nothing short of a miracle. And that is daily chewing like it’s his job. I highly recommend the Acornucopia for aggressive chewers with jaws like hyenas…so it’s probably great for your dog too.
