The Rat CD3 (Cluster of Differentiation 3) ELISA Kit measures CD3 in Rat 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 CD3 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with CD3 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 CD3 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Cute but small
Size: Large, Color: Skinny Green
Cute stuffy and has not yet ripped. While my dogs plays with it, the toy is a bit small for him. For reference he is 120lbs.

After a lot of chewing, it’s still holding up with only minor wear
Color: KING KONG
I have a pit bull, so finding toys that actually last is always a struggle. Most toys don’t survive more than a day, but the PETSTA Indestructible Dog Toy has been surprisingly tough. My dog went straight to it and started chewing right away, and it’s held his attention way longer than other toys usually do. The beef flavor definitely helps, and the toy itself feels solid and well-made, which is exactly what you want when your dog has a strong jaw. After a lot of chewing, it’s still holding up with only minor wear, which honestly impressed me. It’s been great for keeping him busy and stopping him from chewing things he shouldn’t. No toy is truly indestructible, but this one comes pretty close and has lasted longer than most toys I’ve tried. If you have a pit bull or another aggressive chewer, this toy is definitely worth trying.

Perfect for strong chewers
Color: KING KONG
This “indestructible” dog toy (we call it Muscle Dog 😂) has been amazing! My dogs are pretty aggressive chewers and this thing has held up way better than most toys we’ve tried. They love playing with it and it keeps them busy for a long time without getting torn apart right away. It’s tough, durable, and definitely lives up to the name more than other “indestructible” toys out there. We’ve tried a lot of toys and this one is a winner—perfect for strong chewers!

Great but not indestructible
Color: KING KONG
Great product but it is not indestructible for my aggressive chewer. This is the second time I have purchased because he loves it so much and it keeps him occupied for hours.
