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

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Great toys
My 3-year-old Maltese destroys stuffed toys in short order. These toys with no stuffing keep her busy for hours without the risk of ingesting a bunch of loose stuffing. She loves them and carries them around the house making them squeak. Very durable for a toy destroyer like my little girl.
