Background

Interleukin-21 receptor (IL21R) is also known as CD antigen CD360, Novel interleukin receptor (NILR), is a receptor for interleukin-21 and belongs to the type I cytokine receptor family or type 4 subfamily. Mature human IL-21 R consists of a 213 amino acid (aa) extracellular domain (ECD) with 4 conserved cysteine residues, a fibronectin type III domain, and a WSxWS motif, followed by a 21 aa transmembrane domain and a 285 aa cytoplasmic domain with a Box 1 motif, a kinase domain, and several sites for tyrosine phosphorylation . Within the ECD, human IL-21 R shares 69% aa identity with mouse and rat IL-21 R, respectively. IL21R transduces the growth promoting signal of IL21, and is important for the proliferation and differentiation of T cells, B cells, and natural killer (NK) cells.

Must have for a young puppy
Size: Small (Pack of 1), Color: Blue
Very helpful for our young puppy. Cleaning it isn't the easiest, but cleaning advice is easily found online and it's worth the hassle to have a durable lasting toy around

Our Two year-old Great Pyrenees rescue loves her Lambchop. She’s fairly gentle with it, but it did accidentally rip so we had replace it since she loves it so much. No fault of the product. The product is very well made, She just got a little rough with it.

Excellent for chewers who like to extract squeekers. It has many.
Style: Lambchop, Size: 10"
This was my dog Clarks favorite toy. When he passed away last year, I saved his played with lamb chop and it sits near his ashes. My current dog Walter loves lamb chop too. I appreciate the squeekers in the all the mitts. It really adds so much to this toy. Great design. Durability will always be an issue with soft fluffy squeeky toys. I buy this knowing that half the fun for my dog is trying to extract all the squeekers.

Soft, strong, beautiful toy! My pup's favorite!!
Style: White, Size: 6"
My pups favorite toy is Lambchop!! They're soft, odor-free, and pretty chew-resistant, considering the work out, it goes through! I stay vigilant in keeping them in stock, for her playing pleasure. She enjoys doing her zoomies, squeaking as she goes. Stops, tossing it in the air, to catch it, them off zooming again! Thank You for the care taken in making this adorable toy, for hours of fun for my pup! Please keep them in stock. They're well worth every penny!!
