Background

CD19, also known as B-lymphocyte antigen or Cluster of Differentiation 19, is a single-pass type I membrane protein that contains two Ig-like C2-type (immunoglobulin-like) domains. It is expressed on follicular dendritic cells and B cells, being present from the earliest recognizable B-lineage cells during development to B-cell blasts, but is lost upon maturation to plasma cells. CD19 primarily functions as a B cell co-receptor in conjunction with CD21 and CD81. Upon activation, the cytoplasmic tail of CD19 becomes phosphorylated, leading to binding by Src-family kinases and recruitment of PI-3 kinase. Mutations in the CD19 gene are associated with severe immunodeficiency syndromes, characterized by diminished antibody production. CD19 has been shown to interact with CD81, CD82, Complement receptor 2, and VAV2.

Great little rug!
Color: Ivory White, Size: 2' x 3' (Sheepskin Shape), Color: Ivory White, Size: 2' x 3' (Sheepskin Shape)
This nice little sheepskin rug is the perfect finishing touch to my little reading nook. It’s soft and thick. Follow the enclosed instructions to fluff it up. I was going to order a second one but saw that the price jumped nearly $10 in a week. It’s nice but it’s not worth that amount. I’d buy it on sale though. Five stars.

Unfortunately I can’t recommend it.
Color: Ivory White, Size: Round 48''
I got my carpet time ago but I opened the package just 3 days ago. Unfortunately I can’t take it back anymore. I opened the bag after I had done my daughter’s bedroom with flooring and walls painted. Sadly when I opened this bag the smell was sooooo bad. The material was not soft and the color was more yellow than ivory. The quality is not good. It is thick and the value of the money was extremely expensive which makes more disappointing that I can’t take it back. Not easy to clean and the size was ok. But I can’t recommend it.

Exactly as pictured and described
Color: Taro Purple, Size: Round 48'', Color: Taro Purple, Size: Round 48''
I absolutely love this. I have it under my office chair in my home office and it is so luxurious to feel this under my feet while I'm working. It came shrinkwrapped and took a day or two to fluff back out and lose the creases. It looks great now. I didn't notice any odor when I opened it. Shipping was fast and it was very well packaged. I was very pleased with it. I would definitely buy again.
