Each EasyStep ELISA kit comes with two extra strips of coated wells to run for standard curves ensuring you have more wells for your samples. The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human EFNA1, and the Human EFNA1 standard plate wells that pre-coated using protein-related techniques are provided separately. Standard/Sample Diluent Buffer or samples are added to the appropriate microtiter plate wells ,then added a HRP-conjugated antibody specific to Human EFNA1. After TMB substrate solution is added, only those wells that contain Human EFNA1 and HRP-conjugated antibody will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human EFNA1 in the samples is then determined by comparing the OD of the samples to the standard curve.

Better jeans than I expected
Size: 29W x 34L, Color: Rinse, Size: 29W x 34L, Color: Rinse
I pretty much only wear Levi's 510s & as of lately Asos skinny jeans. Thought I'd give these a shot. I wear between 28w-30w so I ordered 29w. They fit good & seems to be really true to size. I could have probably ordered the 28w for a tighter fit. Only reason I didn't give them 5 stars is that the dye transfers from the denim. I'm sure eventually that will stop happening?? I like the dark denim so I don't wanna continue to wash them so they fade out so soon.

Great jeans for the money. I would say they are as good as Levis. They are sized write and have more waist and inseem sizes. I have 10 pairs probably.
