Background

Epigen, human (EPGN) is a member of the epidermal growth factor family. EPGN is ligands for the epidermal growth factor receptor and play a role in cell survival, proliferation and migration. EPGN Promotes the growth of epithelial cells. May stimulate the phosphorylation of EGFR and mitogen-activated protein kinases. The precursor of EPG is a widely expressed transmembrane glycoprotein that undergoes cleavage at two sites to release a soluble EGF-like domain. EPGN might represent the last EGF-like growth factor and define a category of low affinity ligands, whose bioactivity differs from the more extensively studied high affinity ligands. Recombinant EPGN is expressed by Escherichia coli, composed of 72 (Ala24-Ala95) amino acids.

Incredible quality!!!
Color: Black/Black
We have had these for a little over three months and so far they are still working fantastically. We are amazed at the quality for the price. It makes grinding fresh salt and pepper so easy! Perfect for cooking and topping food.

Works well, just wish it was rechargeable
Color: Stainless Steel
These grinders work pretty well and are really convenient to use with one hand while cooking. The adjustable coarseness is nice and the LED light actually helps more than I expected. They seem well made and hold a good amount, just wish they were rechargeable instead of using batteries. Still happy with them overall.

More than a daily grind
Color: Purple
We are very happy so far, working very well. The grind is even and easy to adjust with a simple turn of the screw on the base of the grinder. The automatic light is a nice feature, especially as I am 66 and my eyes are not what they used to be. Once I turned the on button to face front, I'm no longer triggering a grind just by picking these up. (our last grinders trigger was on the top of the unit}. They feel well constructed and are easy to fill. My wife absolutely loves the color (purple). will update this in a couple months for durability, but for the price so far (1 month) 5 stars

Electric grinders
Color: Black/Black
Easy to refill. We use pink Himalayan salt and the grinder does well. It seems to struggle a bit with the peppercorns bit still gets the job done. The light is nice. We have enjoyed the ease of use. It also looks nice on the counter. The holder is great as it catches any fine debris after use. I purchased this one as it uses actual batteries and not something else I have to charge. They have been used daily for 2 months and have not needed to change the batteries yet.
