Description

Rat IL-1ra/IL-1F3 (Interleukin 1 Receptor Antagonist) ELISA KitThe Rat IL 1ra IL 1F3 (Interleukin 1 Receptor Antagonist) 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 IL 1ra IL 1F3. 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 IL 1ra IL 1F3 and Avidin Horseradish Peroxidase (HRP) conjugate are

The Rat IL-1ra/IL-1F3 (Interleukin 1 Receptor Antagonist) 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 IL-1ra/IL-1F3. 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 IL-1ra/IL-1F3 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 IL-1ra/IL-1F3, 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 IL-1ra/IL-1F3. You can calculate the concentration of Rat IL-1ra/IL-1F3 in the samples by comparing the OD of the samples to the standard curve.

Brushes up bedtime routine!
Style: Sonic Toothbrush with 2 Heads
My kids have very weak enamel with tons of cavities. It would take us forever to get their teeth clean because I use the plaque dye tablets to make sure their teeth are actually clean after brushing. Because of this we would spend up to half an hour brushing teeth over and over and over again. With this toothbrush the kids love it first off. Then it has a timer on it so the kids know when they are done brushing and it works great. The kids will use it once and then I will spot check their teeth while we're flossing and I will take a regular toothbrush and hit any areas that this missed. And those are only a couple small areas. Not only does it work great the kids love it and it saves me so much time and headache at night when everybody should be in bed!

No replacement heads
Style: Sonic Toothbrush with 2 Heads
Update **** seller has made replacement heads at super affordable price. This toothbrush is really cute and great for small hands. The timer is only 45 to 50 seconds which is okay but I have to hit it twice to ensure a good brush for my 4 year old. This brand doesn't sell replacement heads for this product which is a bummer. It's not worth the money if you have to buy a whole new toothbrush after 3 months of use. I'd love to see replacement heads in the future!

U Shape Isn’t Great!
Style: Sonic Toothbrush with 2 Heads
Love boka toothpaste and I’ve seen ads for that auto brush so I got this for the u shape head. It sucks. It just vibrates doesn’t actually clean, and it’s silicone bristles not nylon. I had to use a lot of toothpaste to put in the u shape as well compared to a little dab on a brush. The handle is cute.

Super cute!
Style: Sonic Toothbrush with 2 Heads
This is a super cute toothbrush. My 3 year old loves using her "fruit brush". I wish there was another setting for even lower vibration.
