Multi-Species LTD4 (Leukotriene D4) ELISA KitThe LTD4 (Leukotriene D4) ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Universal LTD4. During the reaction, Universal LTD4 in the sample or standard competes with a fixed amount of Universal LTD4 on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Universal LTD4. Excess conjugate and unbound sample or standard are washed away, and Avidin Horseradish

The LTD4 (Leukotriene D4) ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Universal LTD4. During the reaction, Universal LTD4 in the sample or standard competes with a fixed amount of Universal LTD4 on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Universal LTD4. 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 LTD4 in tested samples can be calculated by comparing the OD of the samples to the standard curve.

love the color and true color of these earrings!
Style: January - Garnet
I am lucky to have a red birthstone because red is my favorite color! These earrings did not disappoint me, the red stone is not huge but I wanted small earrings that would still show up and give me a little sparkle. These earrings match the necklace I got first with the same design. I am happy with these pretty earrings. I also appreciated the good price and quick delivery and will buy from this vendor again.

Rapunzel earrings
Style: June - Alexandrite
I got these earrings as a gift because we were going to Disney and I wanted to dress up like Rapunzel and these were perfect for the look. They are also small and comfortable.

Cute but Wrong Color
Style: July - Ruby
These earrings are really dainty and pretty, and my daughter loved the style. Unfortunately, the color wasn’t quite right for her birthstone—her ruby birthstone is a deeper red, but these leaned more toward red-orange. They still look nice and could work for other occasions, but we were a bit disappointed since we were hoping for a true ruby match.
