The EFNA5 (Ephrin A5) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human EFNA5. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human EFNA5. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human EFNA5, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human EFNA5 in the samples is then determined by comparing the OD of the samples to the standard curve.

My dog loves this.
Color: Black Green, Size: 6 Inch, Color: Black Green, Size: 6 Inch
I have a large Cane Corso who could obviously shred this but, she loves it. This ball is holding up really well. We use it for outside play and she loves batting it around and swinging it from the loops.

Great play and chew toy!
Pattern Name: Star
The dogs love these! They're sturdy and give them plenty of chew time. The size is great and they are very playable. The dogs have a lot of fun and the weight is just enough for our little dogs.

Great Dane Tested and Approved 5 Star
Pattern Name: Checkered, Pattern Name: Checkered
A picture is worth a thousand words applies to this product, as you will see in the attached photos these stand up to the abuse of a Great Dane. He has dragged me around the yard for hours already with this in his mouth and the stretchy handle keeps it shape. This ball is a little firmer than others of these I have had in the past, which helps exercise his giant jaw. I could get a few weeks out of the other brands I have bought. This brand is still like new well past the time others have failed. I will be ordering more as my French Mastiff is interested in one of his own (the boys do not like to share toys - most dog guardians understand).

Holding up well.
Pattern Name: Checkered
Seems to be holding up to my aggressive chewer. I have it hanging from a tree branch and she loves leaping to get it! Buying another pair so she has a greater selection around the backyard.
