The HAND2 (Heart And Neural Crest Derivatives Expressed Protein 2) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human HAND2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human HAND2. 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 HAND2, 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 HAND2 in the samples is then determined by comparing the OD of the samples to the standard curve.

Great toy but never received the replacement they offer.
It’s is a very durable toy. But not indestructible. My dog loves the ball and it did last 4 months which is much longer than any of his other toys. I emailed the company to see if they honored their one time replacement policy for Amazon orders. I was told they do and was told I was shipped a replacement. But we never received it. We’ve ordered plenty from Amazon before and after this so I don’t know where the hold up would of happened but here we are. I did email the company back and told them that I didn’t receive the replacement and asked if they could verify my address….but they haven’t responded. Just sucks. Would of been great if I actually got the replacement!

My HEAVY chewers favorite ball
It's dense and has some weight to it, can definitely get good distance when throwing and it bounces a long way. It's soft enough for my dog to chew on but tough enough that even with her destroying every toy I get her she looses these before ever tearing into them. About softball size.

Safe
I normally don't write reviews but these products deserve the effort! I bought 4 different black toys from this Brand and all are still intact after 6 months heavy usage by 2 aggressive chewers (a Belg Malinois & black Lab), fantastic products and unlike so many other brands promising to be indestructible, these are the first toys that were not eaten within a month. No more visits to Vet to pay for Xrays after digesting plastic or rubber from badly made toys. Highly recommended.

Your fur kid will thank you!
Color: Yellow Green, Size: 6 Inch
My dog absolutely LOVES this toy! I recently adopted a rescue & wasn’t sure what she might like, so I bought this in a 6” size for a 50# shep/lab/hound. The ball comes with a cute little pump with needle which only takes a few seconds to inflate. I put the ball outside for her; she wasn’t sure of it at first but it didn’t take her long to realize how fun it was to throw around & chase. She throws it up in the air by the loops & runs all over the yard with it & it’s so comical to watch! It seems pretty durable & well made - I’m shocked she hasn’t punctured it by now, but if she does I will definitely buy her another….and another. This is easily her favorite toy. I highly recommend it for your fur kid - you won’t be disappointed, & neither will they..
