The Human SFRP4 (Secreted Frizzled Related Protein 4) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human SFRP1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human SFRP1. 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 SFRP1, 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 SFRP1 in the samples is then determined by comparing the OD of the samples to the standard curve.

Good Toothbrush for cats
The toothbrush works great! My cat actually enjoys getting his teeth brush. Probably doesn't hurt that he gets a treat each time we brush his teeth. His gums look good and teeth are white!

Must have for pets dental care!
These toothbrushes are perfect! My kitten had gingivitis and the vet said I could brush her teeth with a normal toothbrush but I’m so glad I got these instead! As you can see in the video the bristles go all the way around so I basically just put it in her mouth and she does most of the work for me! I also appreciate it’s small, she’s a tiny kitten so it’s perfect for her. These are a must if you need to brush your pets teeth. See the video for yourself! It’s a no brainer!

Good size brush-suction isn't great
The brush itself is a good size and I like that it is round so it's easy to brush. I wasn't as lucky as others to get my cat to start chewing on their own so it will be a process to get my cat used to it. For the brushes itself, it's a good deal for the price. The suction holder doesn't work well at all and only holds some of the time.

Helps my cat brush his teeth
I’ve now purchased these twice for my sweet boy. He loves to brush his teeth with these! They aren’t as durable as I’d like, but also my boy is a super chomper. I wish they were just a bit cheaper!

Works great on removing food particles from your cats teeth, especially when they bite down on it!
My kitten wanted no part of me, brushing his teeth. In fact, I tried to use a feline soft toothbrush, and I ended up making his little gum on his main fang bleed, I felt horrible about it! So when I discovered these and saw how soft they are, I bought these! My kitten started biting it right away and now loves his new ritual, biting on it and letting me gently rub along his gums, it actually grabs food particles when he bites down on it! He seems to loves the feeling of it, as I brushed his teeth, at at 3-5 times a week with it. He has become really good about letting me use it. He does loves when I also rub it along his jaw/gum area as it stimulates those nerve feel-good nerve endings. A winner with my boy Otis!🐾💕
