The QuicKey Pro Canine Estradiol ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Canine E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Canine E2 are added to the micro ELISA plate wells. Canine 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 Canine E2 in the samples is then determined by comparing the OD of the samples to the standard curve.

Great for sensitive skin
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I usually have problems with fragrance in almost any face cream or sunscreen, and my skin reacts very easily, so I’m always careful with what I use. I tried the COOLA Organic Face Sunscreen SPF 50 Sunblock Lotion (Fragrance Free) and I’m honestly impressed. It feels very light on the skin, doesn’t irritate my face at all, and finally a sunscreen that doesn’t have that strong smell that usually bothers me. It absorbs well, works great under makeup, and gives good daily protection without feeling greasy. If you have sensitive skin or issues with fragrance like I do, this one is definitely worth trying.

Love this sunscreen
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I would love to buy again, but I go through sunscreen, I have to find a little less expensive one. No burn, dewy not greasy look. Great for mature skin. No fragrance, works well, melts right in the skin. I do love this product and the spray too!

Light and works with no eye stinging.
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
I love this sunscreen. I wear co tact’s and most sunscreen ends ups burning my eyes. This does not! It has a nice cucumber smell and it’s not sticky or heavy. By far the best face sunscreen that’s light, smells nice, doesn’t burn my eyes and works.

My all time fave sunscreen!
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
This is the best sunscreen! Does NOT burn my eyes like 95% of other sunscreens do. Does NOT break out my sensitive skin, or my sister who has the most sensitive skin ever! It goes on smoothly due to its nice texture, does NOT feel greasy. Wears great under foundation as well. Thank you Coola for such a great formula at an affordable price. I have turned so many 'sunscreen snobs' into fan favorites of this as well. If you haven't tried it, you should!

good for non-white skin
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
Moisturizing, non-sticky, works for my sensitive skin. It's transparent and doesn't leave a white cast on my light brown skin. Smallish size is good for travel and purse. It's a little shiny; wish it came in matte.
