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

It's an okay lotion
Size: 10.14 Fl Oz (Pack of 1), Size: 10.14 Fl Oz (Pack of 1)
It can as advertised, it has no scent but it makes my skin smooth and soft but it's not moisturizing so it's best to use an oil after. It actually tighten my skin over time.

This product is the real deal.
OMG. This is the best skin care product I have ever used. I'm 61 years old and my skin was showing sun damage, dark circles, real wrinkles around my eyes, lips, and forehead. Basically, I was looking every bit of my 61 years. About 30 days ago I started using this organic beef tallow with raw honey moisturizer in conjunction with a product to clear the pores on my nose. (That's a different review.) I will never go back to the 5, costly products I was using. I was using a daytime moisturizer with SPF, a dark circle cream, a dark spot remover, a fine line product, and a night time resurfacing cream before trying this product. That was a couple hundred dollars every 5 weeks or so. Since starting this beef tallow and raw honey 30 days ago, my skin looks 10 times better. It's dewy but not greasy. My makeup looks good ALL day. My wrinkles are less noticeable and, I think, reduced in depth. My under eyes look so good. No more concealer under my foundation. In fact, I can go out and about with no makeup now! This product glides on easily, no dragging or pulling. It never feels greasy. And it only takes about a marble sized amount for my full face, neck, and decolletage. I use it morning and at night. So far, the little jar is still 3/4 full. Amazing product. I will be buying more for sure. Oh, one more thing. About 2.5 years ago, I had to have a mass removed from the left side of my neck. The scar was very noticeable. This cream is even improving that! Try it. See if I'm wrong!

Worth it
I am honestly blown away by this product. My skin feels so soft. I also feel as a mature lady that my lines have softened. My daughter burned her hand very badly and we were using a prescription cream for 2 weeks with little improvement. I used this and seen huge improvement in just days. It doesn't feel heavy or greasy and absorbs nicely. The smell is mild and pleasant. My teenage son has started using it for skin irritation and just 2 days and he's impressed. The jar has seemed to go a long way especially for 3 ppl using it. 10/10 will buy again. I am not paid for this and am a real human.

Triggers rocasea
It isn't as greasy feeling as I thought it might be, and it smells good and feels nice and creamy. I have slight rocasea, and the product made my skin turn red and burn a little. I'm not sure whether I should continue using it. It might be great for people without rocasea.
