Description

Multi-Species 5-HIAA (5-Hydroxyindoleacetic Acid) ELISA KitThe 5 HIAA (5 Hydroxyindoleacetic Acid) ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Universal 5 HIAA. During the reaction, Universal 5 HIAA in the sample or standard competes with a fixed amount of Universal 5 HIAA on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Universal 5 HIAA. Excess conjugate and unbound sample or standard are washed away,

The 5-HIAA (5-Hydroxyindoleacetic Acid) ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Universal 5-HIAA. During the reaction, Universal 5-HIAA in the sample or standard competes with a fixed amount of Universal 5-HIAA on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Universal 5-HIAA. 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 5-HIAA in tested samples can be calculated by comparing the OD of the samples to the standard curve.

Nice shoes!
Size: 11, Color: Black Full Grain
I bought them in black and I like them so much I will be buying the brown soon. They fit true to size and are comfortable and stylish. I like the clean simplicity. They're basically a dressy sneaker which is perfect for my job's 'dress code'. Yet they're stylish enough to be worn weekends or a night out. They seemed just a touch stiff out of the box but IMO that's completely normal and fine - after just a couple days of wearing them they are breaking in nicely. No complaints on that. They seem to be of very high quality and I'm very happy with them.
