The Guinea pig SPTBetaN4 (Spectrin Beta, Non Erythrocytic 4) 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 Guinea pig SPTBetaN4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Guinea pig SPTBetaN4 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 Guinea pig SPTBetaN4, 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 Guinea pig SPTBetaN4. You can calculate the concentration of Guinea pig SPTBetaN4 in the samples by comparing the OD of the samples to the standard curve.

Works great in my setup
I got this for my work desk, and it does exactly what it's advertised to do: it holds my laptop (which is 16 inches). And it doesn't wobble and shake whenever I type on my external keyboard (I use a Unicomp Ultra Classic, which uses buckling springs, so I'm putting a decent amount of force into each keypress - if a stand is not stable, it will be immediately obvious to me), and I can even move my mouse underneath the stand without running into any problems. (Before, when my laptop was sitting directly on the desk, it was annoying how it made me move my keyboard around and inhibited my range of mouse movement, but now I can place my keyboard right where I want it and use my mouse as I please.) The stand feels very sturdy and well-constructed, and it keeps my laptop at eye level. Height-adjust would be nice, but I have yet to find a good quality adjustable laptop stand, so I'll just use books to adjust it if the need arises. The box it comes in is also quite nice. This thing freed up desk space where I needed it and is unlikely to ever fail (there are no moving parts), so I wholeheartedly recommend it to anyone looking for a laptop stand.

Beautiful design
Simple, functional and beautifully designed, I'm glad I bought it. (not a five starts just because I thought it was higher, but again, my fault for not reviewing the specs first)

Not Your Average Laptop Stand
One of the things that I always worry about with stands for my computer is how sturdy they will be. If they aren't sturdy, they aren't really worth having. This is super sturdy -- I don't feel any bounce or flex when I work on it. It's also super well made and looks good sitting on my desk. Both of those things make this one of the best stands that I've used. I just wish it were adjustable.
