The Bovine TNF-Alpha ELISA kit is a sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Cattle TNFa. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Cattle TNFa. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Cattle TNFa, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Cattle TNFa in the samples is then determined by comparing the OD of the samples to the standard curve.

Best cold brew ever
Color: Black, Size: 40 oz
How did I live without this?? My ice coffee made in this is the best I have ever had. It is very easy to use and also very easy to clean. I was very impressed with the quality of the pitcher. It is very thick acrylic and cleans up great with absolutely no staining or discoloration. I am going to be ordering another for my brother! I highly recommend this one!

Very nice but -
Color: Black, Size: 64 oz
Got it today. Just put it to use and made some cold brew. Looks nice and sturdy and doesn’t leak. Has a great large capacity to make a lot of cold brew. Lid closure is great and seals nicely. Very easy to use and user friendly. The plastic material is very thick feeling so that tells me it will withstand quite a bit. I like it so far. My only issue is as soon as I opened the box and pulled the spoon out, it was broken. The bottom stand is completely broken and barely stands up. So that’s disappointing. Otherwise, seems very nice.

Reliable and Easy to Use Cold Brew Coffee Maker
Color: Black, Size: 40 oz, Color: Black, Size: 40 oz
This cold brew maker is easy to use and does the job well. I get smooth coffee every time without bitterness. The size is good and fits in my fridge without taking much space. The filter works well and keeps most of the grounds out of the coffee. Cleaning is simple and does not take much time. The build feels solid for daily use. I like that I can control how strong the coffee is by changing the water and coffee ratio. One thing to know is that you need coarse ground coffee for best results. (I use Bizzy coffee) Letting it steep longer makes the flavor better. It is not insulated, so you should keep it in the fridge while brewing.

Best cold brew brewer out there
Color: Black, Size: 40 oz
One of my favorite purchases in a long time. This coffee maker is just a perfect size and it can be put in the fridge in any direction, on its side, on its top, whatever. It does not leak and it's very easy to clean. Just a superior product all the way around.

Great cold brew maker!
So far this has been a big improvement from a different brand cold brew maker I had. It is simple and easy to used doesn’t leak. The coffee comes out tasting great! It has a smart design that works well. It’s a great deal for how well it works. It is big enough to last all week but not take up to much space in the fridge.
