Each EasyStep ELISA kit comes with two extra strips of coated wells to run for standard curves ensuring you have more wells for your samples. The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human NT-ProBNP, and the Human NT-ProBNP standard plate wells that pre-coated using protein-related techniques are provided separately. Standard/Sample Diluent Buffer or samples are added to the appropriate microtiter plate wells ,then added a HRP-conjugated antibody specific to Human NT-ProBNP. After TMB substrate solution is added, only those wells that contain Human NT-ProBNP and HRP-conjugated antibody 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 Human NT-ProBNP in the samples is then determined by comparing the OD of the samples to the standard curve.

Great ball but easily broken
Size: Large
I got this ball for my two dogs, one is a 90 pound yellow lab mix and the other 45 pound black lab mix. So far only my bigger dog has played with it and has also busted it. He was playing with it for probably half an hour just chomping down to make it crinkle and crunch. It's quite the loud ball!! I noticed the sound wasn't as loud so I took a peek and noticed my dog basically crushed the inner ball into a much smaller ball. He's still having a good time with it though. It's only a matter of time though that he's going to chew the outer shell because it doesn't make noise like it did.

Dogs go for this ball every time
Size: Large, Size: Large
My Boston's and Rotti love this ball. I had to get two more. It's great for the Boston's because they can grasp it with the way it's made with the softer rubber. They love the crackle sound. It's just the right size and weight for smaller like the Boston Terrier and Rotti. Easy cleaning, rinses right off.

It's a Hit a Our House!
Size: Large
My strong chewer is still ..... Well, going strong! He loves his new crackle ball. He enjoys the new sound, the bounce back feeling in his jaws when chews. Mom is happy that pup hasn't put a dent in the toy yet! Price was more than reasonable too. We give it 5 Paws Up!

Chew toy that will last!
Color: Blue&Red Fish
Great toy for a real chewer. It's been in the house for about 5 days and the toy is still intact and the squeaker is still squeaking.
