The Rat IFN-Beta (Interferon Beta) ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat IFN-Beta. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat IFN-Beta 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 Rat IFN-Beta, 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 Rat IFN-Beta. You can calculate the concentration of Rat IFN-Beta in the samples by comparing the OD of the samples to the standard curve.

Looks and feels great...if it only kept running...
Color: Black/Black/Blue
Looks great, feels great...Stopped running about 1 month after purchase. Timex wanted me to send it back (my cost) so they could fix it. I passed. Bought extra coverage, said it was still under manufacture warrantee. Learned my lesson...no more Timex watches.

Timex expedition north traprock
Color: Black/Black/Blue, Color: Black/Black/Blue
Other reviewer said it feels like plastic. It is plastic, or bio-ceramic, which is basically plastic. Light on the wrist. Very comfortable. Does it feel cheap? That's up to you, but it looks really good. I'm happy.
