Description

Sheep FRS3 (Fibroblast Growth Factor Receptor Substrate 3) ELISA KitThe Sheep FRS3 (Fibroblast Growth Factor Receptor Substrate 3) 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 Sheep FRS3. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Sheep FRS3 and Avidin Horseradish Peroxidase (HRP) conjugate are added

The Sheep FRS3 (Fibroblast Growth Factor Receptor Substrate 3) 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 Sheep FRS3. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Sheep FRS3 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 Sheep FRS3, 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 Sheep FRS3. You can calculate the concentration of Sheep FRS3 in the samples by comparing the OD of the samples to the standard curve.

Deceptive Advertising
There's a little bit of false advertising going on here unless you thoroughly read the description. There are three balls in the picture, but you are only purchasing two. Always read the whole description before buying!

Not the same rubber.
I just received these today. I already have two of the same size direct from the local pet store. The one thing I liked about them that made me want to buy more - my 13lb dog could chew on them all night and never leave a mark. The red one I received was as expected. The blue one I received was not made out of the same rubber. It was softer. We played catch a few times and it didn’t bounce the same. I looked away for 5 minutes and she had it already starting to shred. Not sure what happened but 1 of the 2 balls I was sent was not up to par, possibly defective.

Best ball toy I have found
Size: Small
This is my dog’s absolute favorite. I bought this one as a replacement. Finally after years of use one of the tiny ribs gave way. Ball is still completely useable, but got another. She chomps down on it constantly, tears at it, shakes it in her mouth. It is extremely durable. One of the great things about this ball is how ‘soft’ it is. Meaning the way it’s constructed makes it have a lot of give. The texture of the ball itself is firm, but the amount of ‘airiness’ means you can throw it inside your home, against walls, furniture, etc without worrying about any damage. Great toy inside and outside. Highly recommended ball toy. They make all different sizes. My dog is 25 lbs and loves both the 3” and the mini. The mini ones are the same size as mini tennis balls..problem is she would destroy a mini tennis ball within a day of getting one. She has had the mini Hol-ee Roller for years. Super durable.
