Rat COL4Alpha1 (Collagen Type Ⅳ Alpha 1) ELISA KitThe Rat COL4Alpha1 (Collagen Type Alpha 1) 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 COL4Alpha1. 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 COL4Alpha1 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to

The Rat COL4Alpha1 (Collagen Type Ⅳ Alpha 1) 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 COL4Alpha1. 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 COL4Alpha1 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 COL4Alpha1, 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 COL4Alpha1. You can calculate the concentration of Rat COL4Alpha1 in the samples by comparing the OD of the samples to the standard curve.

Buttery soft, comfortable and the perfect height!!!
Size: 10.5, Color: Black Leather, Size: 10.5, Color: Black Leather
I ripped these out of the box as soon as they arrived lol 😂 I knew they were the black knee high boots that I wanted to have as a staple in my Fall closet. They did not disappoint! The stitching is impeccable, they are buttery soft from top to bottom, they are the signature San Edelman design, the heel is perfect – it’s not clunky it’s sleek, but it’s not too high so you can wear these with pants and dresses and skirts. They are VERY COMFORTABLE!!! They are pointy - but I sized up a half so they are not squeezing my foot at all. I can move my toes around and there’s enough space for socks if I need to wear them. I am in ❤️!!!

These boots were made for walking…
Size: 9, Color: Chocolate Brown
Stylish black suede boots with an adorable chunky heel. The fit is true to size. They look elegant yet dangerous! They were also, surprisingly, very comfortable!

My favorite boots ever!
I searched forever to find the perfect camel boots and could not be happier with this purchase. So happy, in fact, that I bought another pair in a different color! They’re really soft and the perfect heel height to still be comfortable. They are so classy and definitely a staple for me for work. Love!
