The F-E3 (Free Estriol) ELISA immunoassay kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with F-E3. Standards or samples are added to the appropriate micro ELISA plate wells then with a biotin-conjugated antibody specific to F-E3. Next,Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of F-E3 in the samples is then determined by comparing the OD of the samples to the standard curve.

Spray stops working
Size: 5 Ounce (Pack of 2)
I’ve been buying this product for awhile and keep experiencing issues. It protects your skin well but is sometimes hard to spray and half the time the nozzle stops working while there is still product in the bottle.

Pricey but works
Size: 3 Fl Oz (Pack of 1), Style: SPF 100
It works well and is definitely worth it, but it's pretty small and pricey for what you get.
