The Human (FSTL4) Follistatin-related Protein 4 ELISA Kit measures Follistatin-related protein 4 in samples. The plate has been pre-coated with Human FSTL4 antibody. FSTL4 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human FSTL4 Antibody is added and binds to FSTL4 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated FSTL4 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 FSTL4. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

Pass on this one.
It's hard plastic, which doesn't make for a fun experience for either the dog, or our floors. It doesn't stay charged for long either. I wasn't impressed at all...and neither was the dog.

Best dog toy ever
So good I bought another. My dog is obsessed with this. The only downfall is after she has chewed it a bit l, it becomes sharp to open

Fun and durable toy
Lots of fun for this crazy guy! He pounces on it, chases it and has so much fun. The confusion on his face is so funny. He usually gets bored fast, however this ball keeps him quite entertained. The ball holds a charge for a few playtimes so that is also a plus!

Great toy
Color: Blue
Great toy, too bad my Shih Tzu is afraid of it. I love the way the movement is subtle and random.
