The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Rabbit CA4.

The Rabbit CA4 (Carbonic Anhydrase Ⅳ) 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 Rabbit CA4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rabbit CA4 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 Rabbit CA4, 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 Rabbit CA4. You can calculate the concentration of Rabbit CA4 in the samples by comparing the OD of the samples to the standard curve.

Practical, elegant, and very functional.
Size: Paper Towel Holder - Standard Design
I absolutely loved this paper towel holder. It features a modern stainless steel design that looks beautiful in the kitchen and matches everything. The base is quite heavy, so it doesn't slide around or tip over when you tear off a sheet—which is incredibly important. The addition of the spray bottle is an excellent bonus. It’s perfect for keeping water, vinegar, or a cleaning solution close at hand, allowing you to do a quick cleanup while you’re cooking or wiping down the countertops. Plus, it’s easy to refill and use. Another feature I appreciated is the side arm, which helps keep the roll in place and prevents it from unraveling on its own. It is well-made and durable. Overall, it is a very practical product that saves space and makes things much more convenient in the kitchen.

Nice and handy!
Size: Paper Towel Holder - Standard Design
Needed a sturdy paper towel holder for one hand operation. This fit the bill. I really like that I can just put some cleaner of choice in the middle to always have on hand; makes clean up a breeze. Would definitely recommend!

It works
Size: Paper Towel Holder - With Phone Holder Design
It's great for what it is. I love the spring arm that holds the towels from unraveling. It does keep the towels from in raveling. That's the reason I bought it. The only thing I don't like about it is the spray bottle on the top. I'm not saying it's a bad thing. I didn't think I'd use the phone holder and made fun of it. But I actually used it and liked the fact that it did its job well. I just don't like it nor will I use it. The spray bottle is the reason for 4 stars

Return for a reason
Size: Paper Towel Holder - Standard Design
The spray bottle feels very cheap, and it doesn’t stick well down to the paper towel holder. The actual holder is an OK quality it’s very flimsy but it does the job. I would recommend to spend the extra money to get a better one from amazon
