The Human CD44 (CD44 antigen) ELISA Kit measures CD44 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 CD44 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with CD44 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 CD44 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Too small for a lab retriever
Size: For Large & Medium dogs, Color: beige
If you have a large dog, I would not advise buying this item. It is very small. I was concerned about choking. My dog loved chewing on it and it is good quality, but I had to monitor constantly and tossed it the 2nd day due to choking fears. Great, if you have a smaller dog, but not good for lab retriever size!

fake fake fake
Size: For Large & Medium dogs, Color: beige, Size: For Large & Medium dogs, Color: beige
buyer beware. i don't know what this joke of a "dog toy" is but it's not what is pictured. no chance i'm giving this to my dog since i actually care about his well being. this product says that it's made in china, "patent pending" and that's its "safely tested in USA". also there's a weird stain on the inside of the packaging. no thank you, and i'm about ready to see the blood of whoever is behind potentially putting a dangerous toy in my dogs mouth.

Perfect for 5 Yorkies - they always go back to these...
Very durable and I'm always hearing my Yorkies gnawing and chewing on these... They really really like them. I've bought antlers and those plastic keys... But these win... The antlers are natural but I've learned they aren't healthy at all, and they still micro-splinter... The keys are too soft and plastic comes off.... These are perfect and I can see the plastic changing shape but not coming off. Perfect win. Oh, and being bright white I can see them in a dim or dark room so I don't step on them, my robot vacuum sees and avoids them, and I can see if my dogs have any bleeding gums, which they haven't had with these yet.
