Description

Rabbit GKN2 (Gastrokine 2) ELISA KitThe Rabbit GKN2 (Gastrokine 2) 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 GKN2. 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 GKN2 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate

The Rabbit GKN2 (Gastrokine 2) 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 GKN2. 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 GKN2 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 GKN2, 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 GKN2. You can calculate the concentration of Rabbit GKN2 in the samples by comparing the OD of the samples to the standard curve.

Stable and attractive
Item Package Quantity: 1, Color: Black
Love the black, it matches my kitchen well. Very sturdy, more so than the Simple Human one that the tension arm broke. A very good product.

Great paper towel holder
Item Package Quantity: 1, Color: Black
This paper towel holder works well for holding the roll while you pull off single sheets. It's heavy and sturdy.

Passed (my) test: 4/5
Item Package Quantity: 1, Color: Black
I used to have a paper holder affixed to the wall. Obviously, it was stable but not always delivering the size of paper towel that we expected. After redoing my kitchen backsplash that I didn’t want to pierce through just yet, i decided to go for an countertop paper towel holder, and i picked this one (in black) Reviews were decent and i liked that it has an “arm” to hold the paper. So, i put it to the test (see video) Here are my conclusions: 1) Solid built and weighted at the bottom + rubber to prevent the holder from moving around while pulling the paper 👍🏼 2) out of five trials at pulling the paper, i only had one fail (see video) which is still a better ratio than with my wall holder. 👍🏼 3) There are probably cheaper holders on the market, but most of them are not stable and require two hands to pull paper. This one is easy of use with only one hand which is useful while cooking. 4) i like that this holder comes in different colors, to match the kitchen decoration. 5) The hook at the top of the holder is convenient to carry the holder out of the kitchen, to the dining table for example.

Great Product - Exactly what I was looking for
Item Package Quantity: 1, Color: Black
Great product. Love the black color and the look on my counter. The tension arm does its job and the product is stable when taking a paper towel off the roll.
