The Rat LEPR (Leptin Receptor) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat LEPR. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat LEPR and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat LEPR, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat LEPR. You can calculate the concentration of Rat LEPR in the samples by comparing the OD of the samples to the standard curve.

Doggos are excited but...
Size: Large, Color: 9 Packs
My dogs are ecstatic about their new ropes. But they're big and aggressive chewers. These ropes are thinner than the pictures made them look. I'd say they're appropriately sized for dogs up to 35 lbs - and not as great for the large breeds show in the pictures.

Dogs love them.
Size: Large, Color: 6 Packs
My dog loves playing with these toys. I also bought some for my daughter‘s dogs. They really love them. I would say the only downfall is that they shred easily. You’ll find little strips of yarn laying around. But that doesn’t bother me because they get a lot of enjoyment from them. I have bought them three different times.

My Dogs Fought Over These!
Size: Large, Color: 6 Packs, Size: Large, Color: 6 Packs
Pack of 6. I specifically ordered a pack of them so each dog would have their own. They still fought over them. lol I only see two of them now because they have hid them from each other. So far, they are holding up well. Heavy enough to toss to them but light enough not to hurt them. Loved the variety of colors. Only issue I have is they are a little small for my mastiff but still giving it 5 stars because the ad stated it was for medium dogs.

Pawesome variety box!
Size: Large, Color: 9 Packs, Size: Large, Color: 9 Packs
I’m a big fan of this box of tug toys. My dog loves to chew and play tug-of-war, and these have been a great fit for him. The quality is solid, and one box typically lasts us around 6 months. He’s now 3.5 years old, so he doesn’t chew as aggressively as he used to, which helps them last even longer. You get a great variety in this box. It’s honestly like Christmas for him every time I bring out a new toy. I usually grab a couple and let him pick. The different shapes and sizes keep things interesting, and he enjoys all of them. The toys are lightweight but very durable, even for an aggressive chewer like mine. The material is made of thinner rope strands, but they’re tightly woven, which makes them ideal for both tugging and chewing. I also think the texture helps with his teeth and keeps them a bit cleaner. I do keep an eye on them once they start to unravel, since I don’t want him swallowing loose strings. That said, it takes a while for him to break them down, so I’m comfortable leaving them with him when I’m not home. I’ve bought several of these boxes over the years. For the price, it’s a great value—about the same cost as a single tug toy at most pet stores. My dog is about 55 lbs, and these are a great size for him. Even the smaller ones get a lot of use. His favorites are the looped ones and the ones with balls—he gets excited every time I pull one out. I’ve tried other tug toy variety packs, and they don’t compare to this one. If you’re looking for a reliable variety pack for your dog, I’d recommend this one with confidence.
