The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Rat TNF Alpha.

The Rat TNF-Alpha (Tumor Necrosis Factor Alpha) 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 TNF-Alpha. 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 TNF-Alpha 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 TNF-Alpha, 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 TNF-Alpha. You can calculate the concentration of Rat TNF-Alpha in the samples by comparing the OD of the samples to the standard curve.

The truth
Format: Paperback
It’s a good read but tells how to pray against demon warfare but nowhere does it tell how you( the reader) can be delivered!

Gentle on Skin, Great Value

Great quality and easy to use. These dermaplane razors remove peach fuzz and shape eyebrows with precision while being gentle on sensitive skin. My skin feels smoother, makeup applies better, and the 6-pack is a great value. Definitely a great purchase!

I really like these I would buy again
Color: 6pcs, Color: 6pcs
I’m honestly so impressed with these dermaplane razors! They came in a cute little storage bag, which I love because it keeps everything clean and organized instead of just tossing them in a drawer. The variety in sizes is also a huge plus—it makes it easy to use around different areas of your face, especially eyebrows and smaller spots where you need more precision. The blades feel gentle on the skin but still get the job done, removing peach fuzz and leaving my face feeling super smooth. I’ve used a few different brands before, and these are definitely a great value for the price. Perfect for at-home touch-ups without irritation.

Smooth Skin Made Easy! ✨
Color: 6pcs, Color: 6pcs
These dermaplane razors are a game-changer (per my wife) when it comes to at-home facial care. This pack of six razors works wonders on peach fuzz, eyebrow grooming, and exfoliating your face. The blades are sharp enough to get a clean, close shave but still gentle on the skin, making it great for beginners or anyone with sensitive skin. Plus, the ergonomic handle makes them easy to control, which helps with precision when shaping your brows. Compared to other dermaplane tools she's tried, these are definitely better quality and last longer before getting dull. Some cheaper ones she's used before start snagging or feel rough after just a couple of uses, but these stay sharp longer and glide smoothly across the skin. One minor downside is that the cap can be a little loose, so be careful when storing them to avoid accidental nicks. Overall, if you're looking for a convenient way to keep your face fuzz-free and smooth without salon prices, these razors are a great buy. You'll definitely notice the difference in your skin texture and makeup application after using them.
