With about 15 known citations, the F-TESTO (Free Testosterone) ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Universal F-TESTO. During the reaction, Universal F-TESTO in the sample or standard competes with a fixed amount of Universal F-TESTO on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Universal F-TESTO. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of Universal F-TESTO in tested samples can be calculated by comparing the OD of the samples to the standard curve.

Yummy Blueberries I Eat Daily
Size: 1 PT
These are good and rarely have any mold on them. They are in good condition and taste yummy. They usually last for about a week and have a wonderful taste. I enjoy them.

Always the best quality, sweet and delicious, no bad berries in this bunch!
Size: 1 PT
I love these blueberries, they are so sweet and fresh, I eat them like candy, lol. These are not always on home delivery, so I don't buy all the time, but, I love it when Amazon excludes them from "fresh" delivery, I could eat these all day. I never liked blueberries much because of mushy, over-ripe, quality, and these are ALWAYS DELICIOUS!

Flavorful and good quality
Size: 1 PT, Size: 1 PT
Flavorful, big, and overall good quantity! Out of 2 pints, maybe 3 berries were squished... which is better than most grocery stores I've experienced. I wasn't sure what to expect from Amazon delivery blueberries, especially for the amazing price of $0.79 per pint. They were delivered in an insulated foil-lined paper grocery bag with a frozen bottled water inside to keep them cool. The pints were closed with rubber bands around them to minimize spills. I opened the bags within a few minutes of delivery so I cannot say how cold it would stay if I didn't bring it inside immediately, but the frozen bottled water was only slightly melted upon delivery so they had kept well.
