Background

CD99, also known as MIC2 or single-chain type-1 glycoprotein, is a heavily O-glycosylated transmembrane protein encoded by the CD99 gene. It is widely expressed in various cell types, including hematopoietic cells, endothelial cells, and many types of cancer cells. This protein plays crucial roles in multiple biological processes such as cell adhesion, migration, differentiation, and apoptosis. In the immune system, CD99 is involved in T-cell activation, maturation, and the regulation of leukocyte transmigration. It also has a significant impact on tumor biology, as it is often overexpressed in cancers like Ewing sarcoma and certain leukemias. Engagement of CD99 by specific antibodies can induce caspase-independent cell death in tumor cells, making it a potential therapeutic target.

Best toy for our dogs!
Color: Yellow Frisbee, Size: Large
These are great for our labs. They love to fetch and play in the back yard. Loved how sturdy these have been the last few days. The material is tough enough to withstand our boys.

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off. One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again. If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.

My dog LOVES this ball
Size: Medium, Size: Medium
Does your dog destroy tennis balls in seconds? Yes? Then your dog NEEDS this ball! It's squishy like a tennis ball, fits in ball launchers (even the cheap ones) and bounces when it hits the ground. My dog has been literally playing with this ball all day and not a single mark on it! The only bad thing is that it does not float. Definitely worth the money! Put it in your cart!

Perfect for ball demolishers
Size: Medium
The dogs love the chuck it brand. I don’t know what it’s made of but they go crazy over them. Will not play with another ball. Wonder if it’s “laced” with an addictive scent. Have pits. Very durable. Not able to chew to pieces. Last for about 6 months before there is a small break. I keep a back up because when the ball goes missing the house is in chaos. 😆 🤪
