Each EasyStep ELISA kit comes with two extra strips of coated wells to run for standard curves ensuring you have more wells for your samples. The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human EFNA1, and the Human EFNA1 standard plate wells that pre-coated using protein-related techniques are provided separately. Standard/Sample Diluent Buffer or samples are added to the appropriate microtiter plate wells ,then added a HRP-conjugated antibody specific to Human EFNA1. After TMB substrate solution is added, only those wells that contain Human EFNA1 and HRP-conjugated antibody 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 EFNA1 in the samples is then determined by comparing the OD of the samples to the standard curve.

Works for my aggressive chewer
Color: GT-2P
It is extremely hard material! My puppy is 6 month old and rips through everything and these absolutely have lasted longer than any plush toys, bully sticks etc. I honestly didn't think I would like them for her but she definitely aggressively choose on these all the time and they hold up so well. If you have a dog that aggressively choose these work for mine.

My Belgium loved her new toys…. Instantly started to destroy them … I can already tell these will last a while with how tough they are.

Received these chew toys earlier today and my dog latched onto them quickly. He has been alternating playing with these since delivery.

Got for larger pup, but younger/smaller pup likes them more.
Color: GT-2P, Color: GT-2P
I got these to try for our older pup that likes to chew on sticks and is always wanting to bring one inside, but I think he just prefers sticks instead. Our younger pup loves them though and steals them...runs off with one and chews on it...comes back and steals the other to take to her pile of toys for eventual destruction. That's just her nature. Ha ha! She is about 35 lbs. and, though these might be a little larger than I might have initially gotten for her, they are great and work just fine to keep her busy and entertained. I think the value for 2 super tough chew toys that are going to last more than a week is great. The texture of them is good for gnawing, or at least she thinks so. I would get them again but will not need to for awhile.
