The Human OPI (Opiorphin) ELISA Kit measures Opi in Human Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with Opi. Opi in the sample or standard competes with a fixed amount of biotin-labeled Opi for sites on a pre-coated antibody specific to Opi. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. 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. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of Opi in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

Fantastic mattress cover!
Color: 4 Black, Size: Twin XL, Color: 4 Black, Size: Twin XL
My son's bed needed a new mattress cover. The old one was a synthetic material that held stains, had snags and runs and didn't last long. So, I went hunting and found this one. I liked that it was quilted as well as waterproof, nice looking. I purchased one for my son's bed, black. Wow, these are really nice. They fit great and are so much more attractive, completely elevates the bed. They make a bit of noise when being put on the bed but are completely silent when laying on the bed. No more crinkle sound! I was so impressed I purchased one for my bed too! Never going back to the old covers. These will not disappoint.

Great purchase!
Color: 1 Gray, Size: California King
I am really happy with this mattress protector! It fit my mattress perfectly and was easy to put on without constantly slipping around. The material feels soft and comfortable, not stiff or plasticky like some waterproof protectors. I also like that it doesn’t make any crinkling noises when moving around in bed. It gives me peace of mind knowing my mattress is protected while still feeling breathable and comfortable to sleep on. Overall, great quality for the price and I would definitely buy it again.
