The CTRB1 (Chymotrypsinogen B1) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human CTRB1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CTRB1. 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 CTRB1, 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 CTRB1 in the samples is then determined by comparing the OD of the samples to the standard curve.

Cheap but good for what we do!
Color: Dark Blue
I wouldn't play tennis with them -- not that quality. However, we use a chuck-it thrower for our pooch and it's the perfect ball. When she's rips them open it's no big loss. Chinese.

Good Quality but Lose Bounce Over Time
Color: Yellow
Solid tennis balls overall, but after a couple of weeks of daily use they start losing pressure. Still a great deal for casual games or practice.

My dogs are obsessed with these
Color: Multicolour, Color: Multicolour
Red, Molly, and Karma are absolutely obsessed with these tennis balls. They’re bright and easy to spot outside in the grass, hold up surprisingly well during rough play, and don’t immediately shred apart like a lot of dog toys do. Great for fetch and everyday play time — definitely a favorite in our house.

Not Tough Enough
Color: Multicolour
Not as tough as Wilson’s. Easy to be chewed and busted by pet.
