The NPNT (Nephronectin) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human NPNT. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human NPNT. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human NPNT, biotin-conjugated antibody and enzyme-conjugated Avidin 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 NPNT in the samples is then determined by comparing the OD of the samples to the standard curve.

Great quality
Color: Four colors, Size: 5cm (ball only)
I was very surprised that these are as good as the chuck it balls. I have a super chewer and he’s tears balls up except for chuck its and he can’t tear these up.

Awesome price for quality balls
Color: Four colors, Size: 5cm (ball only)
These balls are super bouncy and durable. My dog loves them and for the price these are totally worth it! I think they are as durable as nerf balls and equal in size, and much cheaper!

Rope comes out at the slightest force. Pointless tug toy!
Color: Four colors, Size: 6cm (with rope)
If your dog pulls on these (and why wouldn’t he?), the rope immediately comes out. Turns out they just fuse the ends of the nylon rope together, which is no match for a dog playing tug. Any dog, any level of pulling will dismantle these. We’ve managed to reinsert the rope to a couple of these and KNOT it, which gives you a shorter rope but a toy that can withstand some play. But if I had wanted a DIY toy, I’d have used the balls and rope I already own.
