The Human IL-31 ELISA kit is a sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human IL31. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL31. 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 IL31, 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 IL31 in the samples is then determined by comparing the OD of the samples to the standard curve.

My 2 German shepherds love these good quality last a good bit
Size: Large (Pack of 1)
I buy these for my 2 German shepherds. My male is a heavy chewer and he will spend time with this everyday until he starts to wear it down or makes it into a makeshift shank and I replace it Last about 3-4 months for aggressive chewers. Highly recommend (keeps them from chewing my stuff)

The best bone you can get for pitbulls!
Size: Large (Pack of 1)
Can I give these more than five stars? Please?? They truly deserve more than that! I have bought these bones for the last 2 years for my pitbull mix, who is a very aggressive chewer. Her favorite thing to do is just lay and chew. These bones last FOREVER! She can lay there and chew all day long and they will last her MONTHS! It’s honestly amazing! These are the best bones we’ve ever given her and they are the only ones we’ll buy her! Not only do they last forever, they’re safe and natural too! Best product ever!

Great for aggressive chewers, but small mess
Size: Large (Pack of 1), Size: Large (Pack of 1)
He took it right away! It’s a great size. We’ll see how it holds up ONE MONTH UPDATE: (photo included) He loves it still! Still a bit messy but holding up great and he’s a aggressive chewer 1 WEEK UPDATE (photo update included) The bone is great. He loves it and it’s been holding up great. Our 8 month puppy is a super chewer and 60 lbs. the bone has signs of wear but nothing crazy. I went from 5 stars to 4 stars because whenever he chews the bone, the small tiny pieces of bone/wood go everywhere and they’re sticky/hard and make kind of a mess. But still would get this bone again and highly recommend
