Human SPX (Spexin) ELISA KitThe Human SPX (Spexin) 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 Human SPX. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody.

The Human SPX (Spexin) 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 Human SPX. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human SPX 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 Human SPX, 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 Human SPX. You can calculate the concentration of Human SPX in the samples by comparing the OD of the samples to the standard curve.

I like it
Color: grey, Color: grey
It’s not expensive but well made. The tack thing doesn’t spin. Idea for daily wear with a nice look to it. I gave it a 4 because the tact thing doesn’t spin and I like a larger watch face. All in all I may buy more as fashion watches for daily use.

Not water resistant
Color: silver black, Color: silver black
Have had it less than a month, shower and swim with watch on. Water is under the face. Very disappointed in the quality, I get it is a relatively cheap watch, but quality should be better than this. Will never buy again.

Water is getting into the watch.
Color: silver white
It’s a nice watch. I own pieces from other brands, and I stopped wearing this one for about a month; when I decided to put it back on, it was still running. I found this odd, since it’s supposed to be an automatic watch—meaning you need to wear it to keep it wound and functioning—and it supposedly doesn't use a battery. Another thing: every time I wash my hands, water gets inside the watch, even though it’s rated for a depth of 30 meters. I have my doubts as to whether it’s truly an automatic or not. Does anyone else here own one?
