The microtiter plate provided in this kit has been pre coated with an antibody specific to Human GP39. Standards or samples are added to the appropriate microtiter plate wells then with a biotin conjugated antibody specific to Human GP39.

The GP39 (Glycoprotein 39, Cartilage) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human GP39. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human GP39. 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 GP39, 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 GP39 in the samples is then determined by comparing the OD of the samples to the standard curve.

Value for your money
Style: EcoFetch
It's definitely different from the one I lost. It's taking me some time how to throw the ball correctly. It's a hit and miss but we are getting there. When I do get a good throw, it really wings it out there.

Perfect for active dogs
This is a must-have if your dog loves to fetch. It throws the ball far with very little effort and keeps your hands clean—no more slobbery chuckit balls. Lightweight, durable, and makes playtime much more fun (and less tiring for me!).

Way better than the M size for us
Like most people that have dogs I first went with the M size or Tennis ball size (about 2.5") chuckit for my 65-70 lbs Lab. After having that for a while and my dogs' evolution from liking to chase the ball to wanting to catch it, I started seeing how the M size could cause some life threating problems for my pup. I was on the fence for several weeks when I came across this option that included a 3" ultra ball as well as a 3" fuzzy tennis ball like ball. These balls can fly so much farther with less effort and my furry friend seeming to like them more than the 2.5 inch. It also seems to fit their mouth better allowing them to enjoy 'the game' (you lost by the way) much more. If you have a larger dog or your dog has a big mouth, please trust me when I say skip the 2.5" M size balls. You and your dog will haves much more fun with this 3" size

Chuck it ball launcher
This is great! I have a blue healer that loves it. She will play fetch with the ball all day long. The launcher is easier on my shoulder. I can throw the ball twice as far and when she brings the ball back I can grab it with the launcher without touching a spit covered ball. Awesome buy!
