The Human RRM2B (Ribonucleoside-diphosphate reductase subunit M2 B) ELISA Kit measures RRM2B in Human Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Double antibody-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with anti RRM2B antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with RRM2B bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again 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 RRM2B in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Pup Loves It, Some Other Notes
Color: Orange
We've had this for about six months and my 75 lb, 14-month-old German Shepherd pup LOVES IT. Her favorite is "Crazy Bouncing Mode." In fact, she doesn't care much for the normal mode. She chews it a lot - even drops it in her water bowl at times - and it's still going strong. This is a great purchase. It's nice hands-off entertainment. Do know that it is heavy compared to a normal ball - if your pup likes dropping it on the ground like mine does, it will land with a hard "thud," even with the included sleeve. Hopefully you don't have downstairs neighbors. Also know that the cover that goes over the charging port is removable and your dog may choke on it if they chew it in just the right manner. Definitely only let the pup play with it while supervised. All in all, great toy.

Love these Chuckits!
These are awesome. Haven't broke one yet and the puppy loves it and so does my arm! Doesn't hurt to cast it out. Yay me!

No returns… Confusing description
The seller doesn’t allow returns with this product. This product was much smaller than I expected, and I wouldn’t even re-gift it to a friend with a smaller dog. Why? Because they already tried a similar size and said it kept their hands clean… but gave them tennis elbow.

Captain loves it
So much easier to throw the ball. Pair with the three set of chuck-it balls. My parents can finally throw it far again
