Description

Rat C4 (Complement Component 4) ELISA KitThe Rat C4 (Complement Component 4) 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 C4. 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 C4 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well

The Rat C4 (Complement Component 4) 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 C4. 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 C4 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 C4, 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 C4. You can calculate the concentration of Rat C4 in the samples by comparing the OD of the samples to the standard curve.

These are the only cotton rounds I do not break out with. I use them to cleanse my eyelids along with micellar water for my face. They are great!!

MUST HAVE for me!!
LOVE LOVE!! These are most perfect for make up removal and I use them to apply toner as well. Soft and cushiony. I have tried other styles and they don't compare. There are durable, don't shred when you use them like traditional cotton balls They don't "pill" on your face when using them.

Best Cotton "Pillows" I've Ever Used
How much do I love these soft, thick, and durable cotton pads? I got tired of running out (I use them every day) so I ordered a carton with packages of 100! So simple to use...there's a tiny "pocket" on one side you can put your fingertip in for accuracy, if you choose! They soak up enough nail polish remover to do the job, but are so strong they don't shred like a cotton ball would.

The best gentle pad
I use these constantly to clean my Chinchilla Persian Cats nose which is always leaking. These pads are gentle on his nose and don't shed which I luv. There"s a little slit on one side to use if you want to slip your finger into to hold. These pads are soft on both sides. I dampen them before using. The shape to me is better than the round pads and also the edges are not rough like many round pads are.
