The Rat HRAS (V-Ha-Ras Harvey Rat Sarcoma Viral Oncogene Homolog) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat HRAS. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat HRAS and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat HRAS, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. 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 nm ± 2 nm. The OD value is proportional to the concentration of Rat HRAS. You can calculate the concentration of Rat HRAS in the samples by comparing the OD of the samples to the standard curve.

It Works!
Size: 16 Ounce (Pack of 1), Style: SPF 50
My favorite sunscreen. Smells incredible. Reminds me of the beach every time I use it. Which is daily. Summers are brutal in the south and I don’t get paid enough for a farmers tan. Alba has saved me. I’m hooked on it. Also the price isn’t horrible either. Sunscreen can be so dang expensive. You get your moneys worth.

Defective item
Size: 16 Ounce (Pack of 1), Style: SPF 50
I requested a refund or replacement as one of the two bottles that arrived. Has an issue with spraying. When I put it in the unlocked position, it does not spray I requested from the seller, but the seller wants to meet to provide proof and requesting me to upload a video. When I explained the defect, they told me to move it to unlocked position. I buy this sunscreen all the time for my kids so I’m aware of how to lock and unlock a sunscreen Unfortunately through buyer/seller messaging you’re unable to leave a video so I will unfortunately have to leave a review here. I hope the seller will resolve this defective item.

Go-To for Reef-Safe & Light-Weight Sunscreen
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Favorite sunblock to travel with. Appreciate the simplicity of it, and the fact that it rolls on and rubs in smooth. Of course the iconic scent is also a plus.

Great choice
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
After I suffered a second-degree burn from steam, I was told by my doctor that I would have to keep my new fresh skin sun-blocked for up to a year to avoid any scarring or hyper pigmentation. This has been a great selection as it is a roll-on, Which helps a lot with preventing messes that can happen with traditional sunblock bottles. I also like that it is easy to travel with, and the fact that it is zinc based.
