This ELISA kit is designed to detect Human Tumor Necrosis Factor (Human TNF). The assay plate has been pre-coated with mouse anti-Human TNF-alpha monoclonal antibody. When the sample containing TNF-alpha is added to the plate, it binds to the antibodies coated on the wells. Then, a horseradish peroxidase conjugated mouse anti-Human TNF-alpha Antibody is added to the wells and binds to TNF- alpha in the sample. After washing the wells, substrate solutions are added, and the color intensity is directly proportional to the amount of Human TNF-alpha present. The reaction is stopped by adding an acidic stop solution, and the absorbance is measured at 450 nm.

Size up! Super comfortable!
Size: 10, Color: Black Leather
Super comfortable, can walk al night in them. I size up in anything steve madden. I’m usually a 9, but a 9.5 in steve madden fits almost exact so I get a size 10 in any of their shoes. Sizing is consistent throughout styles but I def need to size up. If you’re in between sizes, I suggest a whole size up. Unless you like an exact fit, personally I think an exact fit looks off any slight movement of your foot and the shoe looks like it doesn’t fit. I would say they’re pricey but they’re def a classy and comfortable pair of heels!
