Background

CD20 is a 33-37 kDa non-glycosylated phosphoprotein expressed on the surface of B cells from the pre-B cell stage through maturity, but absent on plasma cells. It belongs to the MS4A protein family and has four transmembrane domains, one intracellular domain, and two extracellular loops. CD20 is believed to facilitate calcium influx, which is essential for B cell activation and proliferation. Although its exact biological function is not fully elucidated, studies suggest it plays a role in B cell receptor signaling and may act as a calcium channel. CD20 is a key therapeutic target for B cell malignancies and autoimmune diseases, as it is expressed on various B cell cancers and its targeting can induce cell death through mechanisms like complement-dependent cytotoxicity and antibody-dependent cellular cytotoxicity.

indestructible!
these are so cute, squeak but my puppy who chews everything from rocks to shells was unable to tear these toys to shreds or even bite it into pieces. she actually gave up and grew bored with them which has never happened with any other toy or item she fixates on and eventually destroys.

Great!
Surprisingly tough. Holds up to tug and doesn't rip right away like so many soft toys do. Has crinkle legs and squeaky head. Dog is having so much fun

Great quality and flavor

I have two dogs that can chew through everything within a day. Not these, going on four days now, there are signs of wear and tear but still intact. The dogs love the flavor.
