Background

IFN-α is a cytokine that has an immunomodulatory function. It plays an important role not only in antiviral activity but also in several physiologic functions, such as activation of dendritic cells and accelerated expression of major histocompatibility complex I and II molecules that may cause increased antigen presentation. Variants of human leukocyte interferon α 2 (IFN-α 2a, α 2b, and α 2c) differ from each other by changes in their coding regions at nucleotide positions 137 and 170. IFN-α 2a is an important cytokine and used for antiviral and anticancer treatment.

Space saver and works!
Color: Black, Size: 5FT (Flat Plug)
I can't imagine why all surge protectors come with an option to screw them to a surface. I have screed this inside to one of garage cabinet sides an all my tool chargers connected to this. Such a space saver!

Nice oak corner shelf but check your measurements first
5 stars for the shelf, 3 stars for myself :-) This is a well-made oak corner shelf that looks great where I put it. The wood is nice quality and the construction is solid. Before you order though, do yourself a favor and check two things: 1) Make sure the size is actually big enough for what you need, and 2) Check that your corner is actually a true 90-degree angle. Turns out mine isn't perfectly square and now I'm trying to figure out how to position this thing properly. Good product overall, just wish I'd measured more carefully before ordering.

i’ve been wanting this shelf for quite some time and finally decided I’m doing it. I’m absolutely completely satisfied with the size the quality of the wood and the paint job. It’s made very well. I have to say I was surprised at how nicely sanded it was and ready to hang.
