The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Bovine TNF Alpha. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Bovine TNF Alpha and Avidin Horseradish Peroxidase (HRP) conjugate are added

The Bovine TNF-Alpha (Tumor Necrosis Factor Alpha) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Bovine TNF-Alpha. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Bovine TNF-Alpha and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Bovine TNF-Alpha, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Bovine TNF-Alpha. You can calculate the concentration of Bovine TNF-Alpha in the samples by comparing the OD of the samples to the standard curve.

Great shoe for the price
Size: 9, Color: Black
My son needed a dressy pair of shoes. Decided to try these for the price. He loves them and has worn them several times. They still look great and he says they're comfortable. We ordered his regular size and it fit perfect. We’re very happy with this purchase.

Not a great fit
Size: 12 Wide, Color: Dark Brown
I got these hoping to have a good fit and comfy shoe. They do look very nice and some might like them. I got two different brands the same day these and another one ,both the same size and they fit widley different. These have a very long and pointed toe that made that uncomfortable and hard to walk in. I would have to try out other sizes to see if I could find one that fit better but I dont want to go through 5 pairs to get a good fit. That is a downfall of buying online. They did seem to be made well and like I said the looked good but the fit not great.

I purchased these for a show I costumed at the local community theater. The fellow that wore them said they were comfortable and fit well. They look very classy and came as described. Good price for a nice shoe!
