The Human (TPSD1) Tryptase Delta ELISA Kit measures Tryptase delta in samples. The plate has been pre-coated with Human TPSD1 antibody. TPSD1 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human TPSD1 Antibody is added and binds to TPSD1 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated TPSD1 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Human TPSD1. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

Fantastic toy for the pups!
My dog is in LOVE with these toys. I've been buying them once a year for the past few years and although I'm sad to see the price go from $11 to $19, it's a staple toy in our house. Great for treats inside of it for enrichment, peanut butter freezes in the prong great and it keeps my girl busy.

Easily destructible
NOT for aggressive dog. My Boston Terrier is a chewer and had this destroyed in a few hours and it is a choking hazard. I threw it away the same day!!! Do not purchase if your pet is a chewer!!!

Works fantastic.
Works great. I have 2 little dog. Both part min pin. But they can chew. They have tartar and I am trying everything to help them, with powder in the food, and a liquid for the water. That's been helping but they will not let us brush their teeth. SO I know they love bones, but I didn't want them to keep eating them, like the ones for fresh breath and cleaning the teeth. They just eat them and get fat. WELL, these bone here that I bought, are fantastic!!. I only stick a few treats inside the seams and middle and they both chew away getting only a little treat at a time bit they have to work for it. So now they chew longer and get very little treats. Yes, my dogs can chew and they have already done some damage on this bones, but for the price and what it does, Its a win win. I will try to get a video or pics later.

Good Product But I Need Something Indestructible
These were advertised for aggressive chews, but my 2 mini schnauzers puppies quickly bit off the little prongs within an hour. I didn't put food inside them; I just wanted them for chew toys. Well, they were not hard enough for them. The size was perfect for puppies, but they were not durable enough for my 'heavy' chewers. I hate I can't find chew toys they can't destroy! Now they bring in sticks and mess the house up.

Works great with toothpaste.
They lasted longer than most toys but eventually my dog was able to tear them up.
