Description

Human E2 (Estradiol) ELISA KitThe Human (E2) Estradiol ELISA Kit measures Estradiol in 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

The Human (E2) Estradiol ELISA Kit measures Estradiol in 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 E2 in the sample. The concentration of E2 in the sample is then determined by comparing the O.D. of the samples to the standard curve.

Soft non-squeaker
Color: Enno
Our son's dog loved this non-squeaker! Very easy to carry around the house and cuddle with on his bed.

Very disappointed
Color: Enno
The toy was split into pieces in the first 5 minutes of the dog playing with it. Apparently not as durable as advertised.

Dog toys need to be sturdy - maybe you should sew them with a 5-thread machine like a serger?
Color: Elroy
My dog's full size teddy is disintegrating, so I ordered this one. It's very cute, but the seams are really weak. I've already repaired 3 seams in just a few weeks.

Great toy!
Color: Elly
Great toy! Dog loves it and it is durable. We’ve bought other toys that he tore apart within a week, not this one! He takes it everywhere we go!
