The Rabbit UBR4 (Ubiquitin Protein Ligase E3 Component N-Recognin 4) 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 Rabbit UBR4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rabbit UBR4 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 Rabbit UBR4, 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 Rabbit UBR4. You can calculate the concentration of Rabbit UBR4 in the samples by comparing the OD of the samples to the standard curve.

The tennis balls are very well made.
Color: Yellow, Size: 20 PACK
Bought this bag of tennis balls for my son’s dog. He has a tennis ball launcher that he shoots and she runs to get the ball and bring it back. Perfect training toy!

Great value.
Color: Yellow, Size: 20 PACK
They bounce and they float. Color is bright. Great for my dogs. I let my dogs use these instead of the ChuckIt brand when unsupervised because they tend to get punctured.

Great color but destroy easily
Color: Orange, Size: 20 PACK
These balls are easily visible and excellent in situations where green balls may be difficult to find. I only take these balls out to play fetch. The balls only last a couple of fetch sessions before being destroyed.

Great quality and great color!
Color: Yellow, Size: 6 PACK, Color: Yellow, Size: 6 PACK
I bought this pack of six tennis balls for weekend games with my kids and some casual practice, and they’ve been great so far. The bounce is consistent, they feel solid off the racket, and they don’t go flat quickly like some cheaper balls I’ve tried before. They work well on both the court and just for backyard play.
