The Porcine UBR4 (Ubiquitin Protein Ligase E3 Component N-Recognin 4) 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 Porcine UBR4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Porcine UBR4 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 Porcine UBR4, 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 Porcine UBR4. You can calculate the concentration of Porcine UBR4 in the samples by comparing the OD of the samples to the standard curve.

Gotta Buy Them All!!
Scent: Keratin
I currently have these sets: - Rice Water - Keratin - Biotin - Cleanser I have been a hairstylist for about fourteen years and have tried EVERY expensive, professional salon brand product out there that promised great results for moisture, repair, scalp health, etc. and none serve the purpose for more than a day or two. These products have been a game changer. I have very curly, fine-medium strands with high density that is consistently dry, brittle, extremely frizzy, and tends to clump together with most products I have used that promise to repair and assist. I started using the cleanser (I recommend using it ONCE a week at max -- it exceeds the expectations and will leave your hair feeling stripped and dry if you use it too often) to start with, to remove build-up. My hair obviously felt incredibly dry after this, so I washed a second time with Biotin and then finished with the biotin conditioner -- for the first time in years, my hair feels AMAZING. It has been three days since the last wash. My hair typically feels heavy and weighed down after the first day. I usually braid my hair lightly and put it in a silk bonnet and I wake up with it having absorbed any bit of moisture it can, and it still felt like straw. After two uses of the biotin, I am able to go 3-4 days between washes and my hair and scalp still feel light, fluffy, fresh, and my hair is incredibly soft. My curls went from loose, messy waves to finally retaining the curl pattern again. My hair isn't breaking off every time I run a pick through it. I can actually easily detangle it while the conditioner is in, and was able to leave the conditioner in for a treatment overnight and it felt even better. My roommates have been using the various ones I have gotten for us, as well, and expressed really enjoying working with their hair again afterward. It responds well to other products cleanses really well afterward. Just a reminder: Most of these are sulfate free. You will not get much in the way of bubbly lathers from this, but your hair WILL be clean. Work it into your hair for 3-5 minutes before rinsing the shampoo out and even let it sit for a few minutes before rinsing while you do everything else. More does not equal better -- this product goes a long way! We just purchased the Apple Cider Vinegar and Nettle formulas and I'll update if they are not as great as the others!

Buy it!!!! Amazing!!!!
Scent: Rice Water
I purchased the Rice Water set..... And let me tell you, I don't think I will ever go back to using anything else!!! I have only used once as I just got it yesterday, and I am truly blown away by the outcome already!!! My hair is extremely, unbelievably damaged from blonde and excessive heat. It has been breaking and thinning like crazy and really just makes me cry sometimes! (I am also 40 so there's that age factor too. I have just started on several quality vitamins, I've decided I will lay off going to the salon and let the blonde grow out, and I have been avoiding heat for a couple weeks now but it has still been super dry and brittle). Well one use of this shampoo/conditioner set and my hair is SO SOFT, SMOOTH, AND SHINY!!!! Like whaaaaat?!? And it smells absolutely wonderful! Not an overpowering perfumy smell, but just a very soft, subtle, and sweet smell! This is definitely a keeper!!! Buy it girl, you won't regret it!! 🙌🏼🥰

Works right away
Scent: Purple
Perfect for wanting your blonde to be on the white side and not yellowish or brassy look. Great of upkeep in-between salon visits. Hair feels moisturized after and soft. BE CAREFUL as this does STAIN your hands and white in the shower / bath. Rinse it off your hands immediately. Bleach will remove any drops or drips. Has a ton. of pigment in it so everything must be throughly rinsed. (no need to freak out first time but it is a bit messy so be prepared but results worth it)

Great products
The Ordinary Serum Favorites Set is a great way to try some of the brand’s most popular products without committing to full sizes. Each serum feels lightweight and absorbs quickly, making it easy to layer into a routine. I noticed my skin looked smoother and more balanced after a couple of weeks of use. The simple, no-frills formulas are effective and perfect for anyone who wants targeted skincare without the high price tag. Overall, a smart and budget-friendly starter set

Quality products that really work
Very happy with The Ordinary products. My skin is glowing, smooth and my pores are smaller. They are easy to use and a little goes a long way. This is a great starter pack if you are wanting to try the line.
