Background

This antibody recognizes the same epitope as clone 15E8.

CD28 (Cluster of Differentiation 28) is one of the proteins expressed on T cells that provide co-stimulatory signals required for T cell activation and survival. T cell stimulation through CD28 in addition to the T-cell receptor (TCR) can provide a potent signal for the production of various interleukins (IL-6 in particular).
CD28 is the receptor for CD80 (B7.1) and CD86 (B7.2) proteins. When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen-presenting cells (APCs). The CD86 expression on antigen-presenting cells is constitutive (expression is independent of environmental factors). It is generally reported, that CD28 is expressed on 50% of CD8+ T cells and more than 80% CD4+ T cells in human, but during the course of activation some T cells lose this molecule. In general, CD28 is a primary costimulatory molecule for T cell activation.

Great Yard Helper!
So easy to use and affordable! This edger is a great time saver, easy to operate, and relatively easy to adjust although you may need a pliers or screwdriver to help with the adjustment levels, but its not difficult. I would have given this 5 stars but just one thing that is a sticking point for me is I wish this had its own stand or hanger because of its odd shape, it doesn't necessarily balance upright too well. It’s long and the guide wheel in the front sticks out. So, it is always awkward to get it tidy in the garage when not in use. Now maybe this is what it's like for landscapers…I’m not a professional. Just a homeowner doing my own upkeep. With what this costs, I’ll figure it out, and is worth the money.

Came in skeptical, but it's GREAT!
I read all the bad reviews I could on this thing and considered it an acceptable risk considering the price. Assembly was easy and the instructions were fair. Not amazing, but once you handle the edger, the gist is clear. I was skeptical overall that the horsepower and plastic guard weren't going to be enough. I ran it for nearly 45min stopping every 5 or so to check the blade and guard. It stayed tight and I was able to manually turn the blade to make sure it was working right. My front yard and sidewalk have been neglected for a few years. I would sometimes edge it out with the weed Wacker, but couldn't get it as clean as I wanted without breaking a LOT of line. When I was done, I noticed the guard had a lot of soil and grass buildup that I was able to take out easily with my fingers. There were a few times I scraped the sidewalk edge, but the blade is still solid and ready for more! I was surprised at the quality and as you're going over an area, it feels solid and not squirly or out of control. My uses are going to be mostly suburban maintenance on my own yard. If I had more land or something bigger, I would consider something larger. For my yard and purposes, this edger is going to work just fine! Did not notice any issues with the blade getting loose, but stayed aware of it. There is a lock nut that keeps it in place. I imagine over time and switching blades, this is going to lose its locking function, but I already see amazon has replacement blades that come with new lock nuts!

Amazon is wonderful. Edger is not good. Just let you know. Black and Decker very good edger. I should have known. It’s worth trying Amazon. They returned it back quickly, money back. So, I bought from Amazon Black and Decker LE760FF, from them. It worked great, like B&D has the experience to build Edgers.
