Description

Bovine COL1Alpha2 (Collagen Type I Alpha 2)ELISA kitThe Bovine COL1Alpha2 (Collagen Type I Alpha 2)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 Bovine COL1Alpha2. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Bovine COL1Alpha2 and Avidin Horseradish Peroxidase (HRP) conjugate are added

The Bovine COL1Alpha2 (Collagen Type I Alpha 2)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 Bovine COL1Alpha2. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Bovine COL1Alpha2 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 Bovine COL1Alpha2, 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 Bovine COL1Alpha2. You can calculate the concentration of Bovine COL1Alpha2 in the samples by comparing the OD of the samples to the standard curve.

Cheap, very thin, and weak
They are very cheap and very weak. You need to double and triple up to use them, so it isn't worth it.

Great retinol face moisturizer
Palmers always makes a great product in my opinion. This one's no different. It's a retinol that doesn't irritate my skin. I use a moisturizer below and on top. It absorbs quickly but doesn't sit on the skin. It's helped with my fine lines quicker than other products I've used and the price point is unmatched. Great product,not a strong scent, will continue to use.

Very Good
Why did you pick this product vs others?: I have been using this product for 2 days and can see a difference in the appearance of my skin. 40+ this does help with fine lines. I can already see my smile lines appearing less noticeable. A little goes a long way. You don't need to use a lot, or it will look like clown makeup, and you will have to work it in, but it is not a big deal. Also, if you have sensitive skin, I wouldn't buy a product clearly listed as extra strength. It will work as an extra strength product.
