The Chicken FT4 (Free Thyroxine) ELISA Kit measures FT4 in Chicken Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with FT4. FT4 in the sample or standard competes with a fixed amount of biotin-labeled FT4 for sites on a pre-coated antibody specific to FT4. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. Add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of FT4 in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

My favorite sunscreen
Size: 5 Fl Oz (Pack of 1)
The BEST sunscreen I have tried. I LOVE this unscented Coola. It goes on smooth and doesn’t feel sticky at all, you will forget you have it on. It truly is unscented and so light. It’s also effective protection from the sun.

One of the few body sunscreens that doesn't trigger my sensory issues
Size: 5 Fl Oz (Pack of 1)
I have sensory sensitivities, so wearing sunscreen is usually a pretty unpleasant experience for me. I can't stand heavy textures, greasy finishes, or that sticky sunscreen feeling that seems to sit on top of the skin all day. I'm also bothered by mineral and matte sunscreens that dry my skin out. It's very hard to find a sunscreen as genuinely comfortable as this one is. I bought the Coola Sunblock Body Lotion because several reviews mentioned that it actually feels like a regular lotion once applied, but I honestly assumed it still wouldn't work for me. I was genuinely shocked the first time I used this. The texture feels silky and lightweight, absorbs quickly, and leaves my skin feeling soft rather than coated or oily. It really does wear more like a comfortable body lotion than a traditional sunscreen, and I don't notice any residue or oily feel at all, which is amazing. I also love that it's fragrance-free, which makes it even easier for me to tolerate, especially with sensitive skin and sensory issues. Coola Sunblock Body Lotion is one of the very few body sunscreens I've tried that I actually enjoy wearing, and it works perfectly. I am very fair and burn easily, but I had no burning or redness on my first outside day of the summer while wearing this. It's sunscreen that works and that I can actually wear with zero discomfort. Amazing.

Im 63, with fair and sensitive skin. I love this high strength sunscreen that isn't greasy and doesn't have added ingredients and perfumes that bother me and make me break out.

Expensive, but worth it
Size: 5 Fl Oz (Pack of 1)
What's the best sunscreen? The sunscreen you'll use consistently. I like Coola because it feels like moisturizer, not sticky gross sunscreen. It's pricey, but I think you get what you pay for with Coola.
