Description

QuicKey Pro Human Estradiol ELISA KitThe QuicKey Pro Human Estradiol ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Human E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human E2 are added to the micro ELISA plate wells. Human E2 in samples (or standards) competes with a fixed amount of E2 on the solid phase supporter for sites on the HRP linked detection antibody specific to E2.

The QuicKey Pro Human Estradiol ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Human E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human E2 are added to the micro ELISA plate wells. Human E2 in samples (or standards) competes with a fixed amount of E2 on the solid phase supporter for sites on the HRP linked detection antibody specific to E2. Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 ±2 nm. The concentration of Human E2 in the samples is then determined by comparing the OD of the samples to the standard curve.

Best product I have found!!! Love love love it!!
Color: Picotonic Shot
This product And all the other dr Melaxin products are awesome. I have seen visible changes in my skin and my forehead wrinkles or creases if you will have diminished. I have to creases in my forehead and one between my eyes and ai can’t even see that anymore and he one on my forehead has lightened up and is not as prominent. My skin is visible plumper I am 49 and look like I am maybe 38. I have probably spent thousands of dollars on all kinds of beauty products and none work like these!! Definetly purchase hem I just bought my second bottle. I have only been using this for three months and it deminished the wrinkles in that amount of time. Also get yourself the spicual shot as well it is the pink one it's a micro needling serum and you don’t feel tingly and you don’t get red irritated akin like you do with other micro needling products. Definitely buy all their products. If you do I would get their set of skin care with the serums the cleanser, the turmeric exfoliator,therice exfoliator that is awesome all you do it put a few drops where you have black heads and you rub it into your skin in circles and it pulls out the black heads and exfoliates at the same time. I will never buy another product again their entire beauty line is great they have all you would need for beautiful skin.

Brightened My Skin and Helped Dark Spots
Color: Picotonic Shot, Color: Picotonic Shot
I’ve really liked using the Dr. Melaxin Protonic Shot Serum! The bottle is pretty small, and since I used it twice a day it lasted me about 4 months. But one pump is enough for my whole face. My skin feels very smooth after using it, and I’ve noticed some darker spots becoming lighter over time. I’ve also seen a brighter look under my eyes, which has been a huge plus for me!
