The Human (IFNA21) Interferon Alpha-21 ELISA Kit measures Interferon Alpha-21 in samples. The plate has been pre-coated with Human IFNA21 antibody. IFNA21 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human IFNA21 Antibody is added and binds to IFNA21 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated IFNA21 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Human IFNA21. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

It doesn’t stay in
The pipe keeps coming out. Not worth the money. Not sturdy to hold a top table.

Good finish, poor hardware.
Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly. Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration. Ended up running self tapping screws thru parts to complete assembly.

Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

Fantastic for furniture making

Frankly, I didn't know what to expect... But these turned out to be exactly what I was looking and hoping for. These table legs were so easy to assemble. They come with adjustable feet so you can have a level table no matter your tabletop shape or floor situation. Assembly is done with a simple Allen key. Printed instructions are included with simple diagrams that are so easy to follow. Also, the seller provided all the hardware needed and more! They provided multiple black screws of different sizes that fit through the top holes of the legs, making it so easy to screw the leg base into the table top (use an electric drill with a Philips head for that). I had zero issues with any of the hardware provided. The base has a nice smooth black powder coat application on the metal. Shipping was so quick too. Seriously, if you are looking for a low cost, easy to assemble, good looking, and adjustable end table base, get this. I ended up making plant stands with these using some tree slices I had as you can see in my photo. 10/10 highly recommend.
