Background

Siglecs (sialic acid binding Ig-like lectins) are I-type (Ig-type) lectins belonging to the Ig superfamily. They are sialoadhesin/CD169/Siglec-1, CD22/Siglec-2, CD33/Siglec-3, Myelin-Associated Glycoprotein (MAG/Siglec-4a) and Siglecs 5 to 11. To date, no Siglec has been shown to recognized any cell surface ligand other than sialic acids, suggesting that interactions with glycans containing this carbohydrate are important in mediating the biological functions of Siglecs. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface.  In the immune response, may act as an inhibitory receptor upon ligand induced tyrosine phosphorylation by recruiting cytoplasmic phosphatase(s) via their SH2 domain(s) that block signal transduction through dephosphorylation of signaling molecules. Mediates inhibition of natural killer cells cytotoxicity. May play a role in hemopoiesis. Inhibits differentiation of CD34+ cell precursors towards myelomonocytic cell lineage and proliferation of leukemic myeloid cells.

Great Value!
Size: 128GB, Style: Wi-Fi, Color: Silver
My son broke his previous iPad so he had to chip in for his next one and this was the perfect compromise. It’s lightweight and the battery lasts longer than his last iPad. We bought the silver and it’s a nice color. Highly recommend!

great product, not the best price.
Size: 128GB, Style: Wi-Fi, Color: Blue
Good product, my husband was super excited with it for Christmas. It came in pristine condition and I absolutely love that it was repackaged just like a brand new iPad! Great product but giving it 4 stars because I found non refurbished ones for a similar price.

Just Love this.... Read On!
Color: Silver, Memory Storage Capacity: 128 GB, Set name: Wi-Fi + Cellular
Like knew and seems to have been powered on one time only. Apple treat it as a new device. Its spotless and works great. I have had several ipad pro's and decided to by this instead and I actually prefer it. It does everything I could do with my ipad pro 2020 and then some. Its faster, good cameras. The e-sim card works great though I do wish it had a physical sim card slow.. oh well! The battery life is really excellent, it was quick to set up via a transfer from my old device. I added a case that looks like a fancy note book and love it. This helps with drops and scratches. I have not added a screen protector yet. The storage capacity is the same as my old ipad pro, I will never use 128 gb anyways... To sum up, this gets 10 out of 10... and its a great replacement for a ipad pro!
