The AA (Arachidonic Acid) ELISA Kit measures AA in Universal 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 AA. AA in the sample or standard competes with a fixed amount of biotin-labeled AA for sites on a pre-coated antibody specific to AA. 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 AA in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

Vendor support is excellent
Color: 7-in-1 Black, Size: Rechargeable Set
UPDATE 2: The vendor proactively reached out to me and sent me a replacement. The replacement works well so I’ve given them 5 Stars. UPDATE: It really doesn’t ever go in straight so every cork is at risk for breaking off. I lowered rating to two. It ultimately works about 85% of the time. Meh. Works most of the time, but has issues. It wrecks corks much more often than the Brookstone one we had before. It seems to twist in sideways so that it runs along the glass of the bottle neck instead of straight down. This causes it to destroy the corks fairly frequently… and on occasion it destroys it so much that you can’t get the cork out at all. Pros: Quiet Has the bottle sealers and suction. Recharges on base. Cons: Damages corks Sometimes destroys corks to point of not being able to extract them. Goes in crooked.

Great for any wine drinker
Color: 7-in-1 Black, Size: Rechargeable Set
This is really neat and works well. Easy to charge, but read the directions first, and great value. If you like wine, this is a great product.

Great value and works well
Color: 7-in-1 Black, Size: Rechargeable Set
I wasn’t sure this would compare to the name brand one I’ve had for years but it finally died and I needed a replacement. The Circle Joy amazed me with how easily it removes corks, ejects the cork and vacuum seals the bottle when you’re done. Some reviews mentioned they were concerned with durability but it’s still working great and no signs of wear after two months of regular use.

Great value and does the job admirably.
Color: 7-in-1 Black, Size: Rechargeable Set
I have been using this for several months now. Still haven't needed a charge. Love the little knife to remove cover from cork. Love the decanting attachment. Removes cork easily without much noise and then spits it out. Excellent value. Highly recommend.
