Description

Human C4 (Complement Component 4) ELISA KitThe Human C4 (Complement Component 4) 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 Human C4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human C4 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate

The Human C4 (Complement Component 4) 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 Human C4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human C4 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 Human C4, 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 Human C4. You can calculate the concentration of Human C4 in the samples by comparing the OD of the samples to the standard curve.

Unsafe
This looked like a great idea for my energetic pup until I charged it and turned it on. It worked for maybe 3 minutes and she loved it while it was moving. It stopped suddenly and when I opened the Velcro to pull out the ball to check it, it was VERY warm. Unsafe for human or dog. For over $20 I would expect more for a dog toy. Cheap and non working! I will request a refund !

Great For Dogs With High Prey Instincts
My high prey instinct, Husky/Malamute, loves it. The moment it started moving she was on it. Wouldn't let her brother near it. Not noisy. Has USB port so you can recharge it. It's Very cute. Easy to clean you just pop off the covering and toss it in the washer. Great Brain stimulation - that also allows them to get their energy out - without having to talk a long walk in the middle of winter. Just what I was looking for.

Good toy
My dog really loves toys, technically he loves to kill toys. This toy is supposed to be chew proof but after 1 day my dog managed to pry it open where the Velcro is to hold the ball inside and rip the Velcro out. Now when he shakes it the plastic ball comes flying out so it had to be removed. It also gets super slimy after he chews on it. He still loves to chew and shake the toy itself so overall it was a good buy since I don’t have to spend most of my day walking through my house picking up stuffing that he has pulled out of his other toys. He is not a big dog by the way just a Boston terrier with stuffed animal issues lol.
