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

The best toothbrush, and I've tried them all!
Style: Small Dog, Size: 1 Count (Pack of 1)
I have a little 4 year old Maltese and Shih Tzu mix. She has very tiny teeth that are already starting to show signs of dental disease. I know it's important that they get brushed because small breed dogs are more prone to dental and gum problems. But I've tried every little toothbrush out there and it's a battle trying to brush her teeth. And unfortunately she usually wins! This brush is the best. It is soft and round and she completely tolerates it. I put a little doggie toothpaste on it, which she likes the taste of, and I'm finally able to at least move the brush and paste around her gum line. She still fights me a bit, but nothing like she used to. I would highly suggest that you give this toothbrush a try.

Flimsy and snapped easily
Style: Big Dog, Size: 1 Count (Pack of 1)
Snapped in literally under a minute of using it. The toothbrush head is so small and the handle is really thin and flimsy even though it’s advertised for large dogs… I’m so disappointed.

does the job
Style: Medium Dog, Size: 1 Count (Pack of 1)
Its does the job of cleaning my dachshunds teeth. The only issue is that the SMALL and MEDIUM are the same size. Small was okay but wanted something that would cover more area. Picked up the Medium and they are basicly if not the same size....

It’s an okay toothbrush
Style: Big Dog, Size: 1 Count (Pack of 1)
I thought this design was very unique and a great idea when I bought the toothbrush. The handle is sort of harder to hold on to. I like how the toothbrush bristles are very soft and it is flat on the end to prevent back of the mouth injuries.
