Description

Rat T4 (Thyroxine) ELISA KitThe Rat (T4) Thyroxine ELISA Kit measures Thyroxine in Rat samples. Add samples to the pre coated plate. Then add biotinylated antigen. The antigens in the samples compete with the biotinylated antigen to bind to the capture antibody and incubate. Unbound antigen is washed away during a washing step. An avidin HRP is then added and then incubate. Unbound avidin HRP is washed away during a washing step. TMB Substrate is then added and color develops.

The Rat (T4) Thyroxine ELISA Kit measures Thyroxine in Rat samples. Add samples to the pre-coated plate. Then add biotinylated antigen. The antigens in the samples compete with the biotinylated antigen to bind to the capture antibody and incubate. Unbound antigen is washed away during a washing step. An avidin-HRP is then added and then incubate. Unbound avidin-HRP is washed away during a washing step. TMB Substrate is then added and color develops. The reaction is stopped by addition of acidic stop solution and color changes into yellow that can be measured at 450 nm. The intensity of the color developed is inversely proportional to the concentration of T4 in the sample. The concentration of T4 in the sample is then determined by comparing the O.D. of the samples to the standard curve.

Great quality natural brushes to replace plastic
Been swapping out all the plastic junk for natural items. These brushes are great, I use them with dish butter and they work great. So far holding up really well. Plenty of brushes for different needs, we even have a dedicated veggie scrubber now.

Not Bad
This is how the item arrived. The bristles may be a little rough, but if you are expecting this organic alternative to resemble the same convenient quality as plastic or a sponge… I don’t know what to tell you.

Great Set of Brushes for Variety of Needs
Excellent set! Very pleased! You even get an extra head with the dish brush. Sooo much better than plastic imitations! The smaller dark bristled brush is pretty stiff, not sure I would use in my job stick pans, but makes a great veggie cleaning brush! Between variety of brushes, you can reach very thing in variety of situations and shapes! Absolutely love them!

Moldy bristles in less than two weeks.
Mold. Less than two weeks of use and mold. Ew. The wood does not seem like it's properly sealed for a product that is expected to be used with water. I threw them away. Not even worth trying to return as it didn't feel hygienic.
