The KRT40 (Keratin 40) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human KRT40. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human KRT40. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human KRT40, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. 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 Human KRT40 in the samples is then determined by comparing the OD of the samples to the standard curve.

Good sunscreen
I really like the little bit of glow it gives my face. I’ve used it several times while on the water and it has worked well. I’ve not had any skin irritations.

Finish looks great. The light tint makes for a more even distribution. The smell is pleasant. SPF will help protect the face from the sun. I would purchase this again.

Replaced 3 products
This is a very good product. Everyday I use CeraVe lightweight 30 or 50 spf and mix Drunk Elephant D-Bronzi and B-Goldi drops for a tint and shimmer. This is the only “makeup” I wear as I don’t like heavy makeup and prefer just a subtle glow with a daily sunscreen. This product effectively replaces all of those products for me. I put this on to try yesterday afternoon and my husband immediately said “Did you do something different? You look good.” It’s is a little more runny than I expected but applies thinly (as I prefer) and provides just enough tint to cover some of my redness. The glow is beautiful. Love the packaging, the pump is very easy to manage and keep clean. Too soon to know if it will cause breakouts or how well it holds up in the sun (although my other experiences with SunBum have been that it works well). I will update my review if I have breakouts. Buy this! Edited to add: a dermatologist complimented my skin due to this product “your skin looks great, you’re glowing!” I have not had breakouts from using this product. I still use everyday with a little cream blush and mascara and call it good. I stock up when this goes on sale but even when not on sale it is a great price. Still not 100% sure about it’s effectiveness at sun protection although I’m pretty sure it’s better than nothing. Wish this exact product was available in 50 spf. Still a fave!

A tinted sunscreen.
It was really nice. However, it has a strong tint to it and feels like Makeup with sunscreen. Nice, but uninexpected.
