The Rat TNF-Alpha (Tumor Necrosis Factor Alpha) QuickTest ELISA Kit measures TNF-Alpha in Rat Serum, Plasma, Cell Culture Supernatant, Cell Lysate or Tissue Lysate. This kit was based on sandwich ELISA method. The experiment lasted 120 minutes. Capture antibody was conjugated to an affinity tag that was recognized by a specific antibody coated on the QuickTest plate. Add the Cap/Det Ab working solution into each well, then add the standards and pilot samples into individual wells. If the sample contains TNF-α, a capture antibody-TNF-α-biotin-detection antibody complex was formed. After incubation, unbound conjugates were removed by wash buffer. HRP-Streptavidin was added. After washing, TMB substrates were added to visualize HRP enzymatic reaction. 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. The concentration of TNF-α in the sample was calculated by drawing a standard curve. The concentration of the target substance is proportional to the OD450 value.

They actually last!!!!
Size: 9.5 inch (Pack of 1)
My pitties are CHEWERS!! Most toys don’t last more than a few minutes, if they’re decent then maybe a day or two but these sticks are still going strong!! I ended up getting more cause I was so happy they actually lasted and you can’t beat the price!! My older male is a lot more into toys than my female but now we got a 4 month old bully pup who’s teething and tries to chew on everything!! They are slightly big for him as of right now but he can still easily chew on them and is growing fast -it’s more him trying to run with it in his mouth that is a little hard but they do have smaller options - I love that they can just chew on these for hours and hardly make a dent! If you have aggressive chewers these are a great buy!!

One of the best indestructible dog toys we've bought
Color: 5pack, Size: Large
So we adopted a pup in December and she tears up everything! I mean, Everything! My CPAP, garden hoses, trucks seat belt and backup camera wiring. Every single dog toy with stuffing, dismantle them in minutes. So many dog toys say they are are tear proof. nope! We have tons of stuffing all over our 5 acres. Hen m wife bought these. Beside the bones she bought, these are the only things she can't seem to destroy and she loves them!!!!

BEST Dog Toys EVER! JRT approved
Color: 5pack, Size: Large
🌟 🌟 🌟 🌟 🌟 for these toys! We have terriers who have NEVER met a toy they couldn't destroy... until now. We've had them over a week an all 5 are still intact, crinkly, and squeakers squeaking - and they're played with constantly! When I tell you I've never, in all my years of JRT ownership and rescue, had a toy last 24 hours, much less a WEEK? Well, lots of you will know how astonishing that is! We've currently got 5 dogs (2 fosters, anyone looking for a project?) so the package size is perfect. Get 'em.
