The DEFa4 (Defensin Alpha 4, Corticostatin) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human DEFa4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human DEFa4. 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 Human DEFa4, 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 Human DEFa4 in the samples is then determined by comparing the OD of the samples to the standard curve.

Don't let dog drop it!
Color: Angry Octopus
Was great for a minute. My dog dropped it from mouth onto linoleum floor and ... now it won't do anything but beep once. So, waste of money.

Keeps my dog entertained
Color: Blue Octopus
Cute! Kind of annoying but my dog loves it and it keeps her from tearing the house up. It’s probably my dog more than the toy, she tore the Velcro off within a week. I sewed it back up, but she destroyed that too. I wish they had just the octopus plushie I could buy to replace without getting a second motor.

Works as expected…but scared the “stuffing” out of my girl.
Color: Angry Octopus
It’s cute and works as described. Can’t use it because my dog is TERRIFIED of it. 😂
