The Human Anti-PTX4 (Pentraxin-4) antibody ELISA Kit measures Anti-PTX4 in Human Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on indirect ELISA detection method and takes 3h assay time. The microplate provided in this kit has been precoated with antigen. HRP-antibody is used as detection antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add HRP-detection antibody, then it binds with Anti-PTX4 bound to precoated antibody. Wash unbound components and add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Calculate the concentration of Anti-PTX4 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

For tough chewers
This is great for my large puppy. It has taken a beating, and I trim off any hanging or loose pieces of rubber. It has survived the test of time.

We call it the brick.
Great chew toy. Not really made for playing fetch. It’s large and very heavy. Good construction.

Indestructible but hard to get treats out
We have a power chewer and have had the black Kong products for a long time. I opted to try this new design however, the shape makes it difficult for our dog to reach the treat. We have stopped using it since I had to keep digging the treat out for her. : ) The black Kong shaped like a pear works much better for her. Giving this 3 stars overall because she can't really use it well.
