Rat GDF9 (Growth Differentiation Factor 9) ELISA KitThe Rat GDF9 (Growth Differentiation Factor 9) 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 GDF9.

The Rat GDF9 (Growth Differentiation Factor 9) 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 GDF9. 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 GDF9 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 GDF9, 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 GDF9. You can calculate the concentration of Rat GDF9 in the samples by comparing the OD of the samples to the standard curve.

Not for aggressive chewers
Size: Medium, Color: Carrot
This product is pretty strong, but my dog tore it apart in 5 minutes. The size is great, and my dog loved tearing it apart. I wish it lasted longer.

Recommended by my chihuahua puppy!
Size: Small, Color: Waffle, Size: Small, Color: Waffle
This has been a fantastic toy for my chihuahua puppy. She actually carries it around by the tag and loves rolling it over with her nose. It's a little big for her, but she still really enjoys it. The tough edges are perfect for her little tiny shark teeth. I think she'll like this one even more as she begins teething. It's obviously an adorable toy and it has held up really well so far. It does have a loud squeaker if that's something your dog likes or dislikes. Mine doesn't have the jaw strength or size to squeak it, but she likes it when I do it. Considering what I paid and the many low quality toys on the market, this thing is a great value. Highly recommend it for toy and small breed dogs and puppies!

Tough Versatile Interactive & Chew Toy
Size: Medium, Color: Strawberry
Update: the Snake is the absolute best in terms of entertainment value. Provides tugging opportunities and our dog is obsessed with it. Love these toys. This is quite literally one of the only toys we can leave with our puppy as both an interactive and self-play chew toy. Our small puppy (<20lbs) destroys every plush and latex toy in minutes. Has no interest in playing alone with durable toys like Kong and gets bored of them if we don’t play with them interactively. This satisfies our dog’s needs to chew on toys and keeps her entertained when we want a break but also quickly becomes a beloved interactive toy we can play fetch with. Yes, eventually our doggo destroys it as expected since we are using to both as a chew and interactive toy but it takes quite a while and we are very satisfied and impressed. This one stands the test of time.

Good for Enthusiastic Chewers
Size: Medium, Color: Strawberry
I wasn't sure how long this toy would last with my beagle, but it has held up surprisingly well! My dog is rough on toys and usually destroys them pretty quickly, yet this one has survived lots of chewing, carrying around, and playtime. Definitely a great purchase for active dogs and enthusiastic chewers.
