The Human IFN-alpha21 ELISA kit is a sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human IFNa21. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IFNa21. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human IFNa21, biotin-conjugated antibody and enzyme-conjugated Avidin 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 IFNa21 in the samples is then determined by comparing the OD of the samples to the standard curve.

Very cute bag, but not as described in picture. The bag I received is much smaller and does not come with additional coin purse. Disappointed.

Not the same bag
Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
The item I received appears to be a smaller version of the bag without the small wallet that should be included. Do not buy it, and save yourself the trouble of having to return it.

A terrific little purse!
This is the perfect size for any woman who doesn't want to drag around a traditional handbag or shoulder bag. It easily holds a cell phone, check book, credit cards, pens, and other necessities without being cumbersome. Seems to be well-made, too. Good purchase!
