The PRF1 (Perforin 1) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human PRF1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human PRF1. 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 PRF1, 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 PRF1 in the samples is then determined by comparing the OD of the samples to the standard curve.

My favorite!
Best face sunscreen I've ever tried and I've tried a ton. I have very sensitive skin and I've left this sunscreen on overnight and it has not caused any issues no breakouts. I wish it had no fragrance but it doesn't smell the worst and my skin doesn't seem to mind. My husband refuses to wear traditional sunscreen but he loves this one because of how light it feels on your face.

Lightweight, fast application
My go-to face sunscreen now. My favorite for rushed mornings when I don’t have much time. Tried a bunch of options including dove men care, Tula, juice beauty, cerave, laroche posay, and lumin. This and Jaxon Lane Rain or Shine are my favorites. Neither makes your skin feel dry or coated in stuff. This one smells like cinnamon to me. Slight eye burn as the alcohol evaporates, but doesn’t get into my eyes or burn during the day. Pretty good discount on Amazon sometimes!

Lightweight but questionable coverage
I traditionally used the Coola face lotion but had switched to the spray for my body so I figured I’d try the face spray. It doesn’t smell as bad as a lot of the reviews say it does. It also doesn’t really smell “tropical” for that matter, but it isn’t unpleasant. It sprays evenly and doesn’t feel heavy or greasy. My only complaint is I still got a little burnt. Full disclosure: I’m super fair and have to reapply every 30-60 minutes, even without getting wet. So maybe it’s not meant for people with as pale a complexion as me. Or I have to constantly reapply, or put the lotion underneath. But otherwise I really liked it and really like Coola products.

Must have for a hot summer!
My mom saw my aunt using it and was impressed, so she bought it for herself and my sister-in-law. They both love how gentle it feels on the skin and that it’s organic and effective.

Too smelly
I love the idea of a clear spray sunscreen but my daughter says it stings her eyes and the smell gives me an instant headache. I really wanna like this but it’s a no go for me
