The Rat CD81 (CD81 antigen) ELISA Kit measures CD81 in Rat Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Double antibody-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with anti CD81 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with CD81 bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again and add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Calculate the concentration of CD81 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

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.
