Background

CD20 is a 33-37 kDa non-glycosylated protein present on the surface of normal and malignant B lymphocytes and is a member of the MS4A (membrane-spanning 4-domain family A) protein family. The CD20 protein comprises four hydrophobic transmembrane domains, one intracellular domain, and two extracellular domains (a large loop and a small loop), with both the N- and C-termini located within the cytosol. CD20 is associated with several key molecules, including the major histocompatibility complex class II (MHCII), CD40 molecule, B-cell receptor (BCR), and the C-terminal src kinase-binding protein (CBP). CBP interacts with Src kinases such as LYN, FYN, and LCK.
A deficiency in CD20 has been shown to result in a reduced number of circulating memory B cells, decreased isotype switching of immunoglobulins (Ig), and lower IgG antibody levels. It is also linked to various pathophysiological diseases and disorders.
CD20 plays a crucial role in multiple physiological processes and is thus a promising therapeutic target. The CD20 protein product has the potential to enhance drug discovery efforts in related fields.

A little too hard for our dog.
Color: 4 Colors
These are definitely durable balls. They are a harder than our dog prefers. He does play with them a little and enjoys squeaking them, but he doesn't like to play fetch with them and that is primarily the only thing he really enjoys doing with balls.

Cheap but expected, worked as intended, none of them broke.
Size: 1000 Teaspoons
Seems to be cheap quality but what else can you expect for the price? I needed something cheap that would work for cold foods, and these delivered. They lasted me forever and I didn’t have any break, I just didn’t trust them with super hot foods. I will buy again in a heartbeat though because for everything else they work great. They are small spoons that don’t hold much, bend easily, are really lightweight and I wish they came in portions or wraps because after opening they sat there collecting dust through the hole in the box and so I had to transfer them to a closed container for sanitary purposes. Again though, I didn’t really expect anything else, so I’m happy regardless.
