Description

Rat IL-1R1 (Interleukin 1 Receptor Type I) ELISA KitThe Rat IL 1R1 (Interleukin 1 Receptor Type I) 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 IL 1R1. 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 IL 1R1 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each

The Rat IL-1R1 (Interleukin 1 Receptor Type I) 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 IL-1R1. 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 IL-1R1 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 IL-1R1, 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 IL-1R1. You can calculate the concentration of Rat IL-1R1 in the samples by comparing the OD of the samples to the standard curve.

Sturdy and long lasting.
These balls are a favorite of my Sheltie! She loves to chase after them and catch them in the air. My dog is not a chewer so I can't say how they hold up under aggressive circumstances! They do last a long time .

Very versatile and durable dog toy
This is not a good toy to leave wit big dogs unattended. That being said it is a GREAT dog toy for households that have a variety size of dogs. Our Golden Retriever and 6 pound Pomeranian both play with it. Both retrieve it and occasionally share carrying it back to us. I know it will eventually get destroyed but that is what dog toys are for. Very durable and with the holes, it allows small dogs to pick it up as easily as larger dogs.

Keeps my dog busy
This works great for rolling treats up in fleece and putting them in the ball. The ball material is flexible and durable. This is a fun and engaging activity for when the weather prevents outside fun.

The best dog ball EVER!!!
Our 3 y.o. Mini Australian shepherd destroys every toy that she can. We can’t have any kind of cloth toys, including the heavy duty, triple stitched, fire hose Kong toys. We can’t have rope toys, even the balls. There are many rubber or silicone toys we also can’t have as she destroys them as well. She has 5 of these balls, some for over a year and they are still in GREAT shape. Left in the sun, rain, etc, they just hold up. They also don’t have a lot of surface area to hold slobber so your hand doesn’t get all wet. Heavy enough to still throw a fair distance, but light enough that the dog was fine the few times I’ve accidentally drilled her in the ass. These are the best.
