The Guinea pig GTF2A1 (General Transcription Factor IIA, Polypeptide 1) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Guinea pig GTF2A1. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Guinea pig GTF2A1 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Guinea pig GTF2A1, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Guinea pig GTF2A1. You can calculate the concentration of Guinea pig GTF2A1 in the samples by comparing the OD of the samples to the standard curve.

Finally a chew toy my aggressive chewer can’t destroy
Color: Grilled color
I’ve gone through countless “indestructible” dog toys that lasted maybe a day—sometimes only minutes. My dog is an aggressive chewer and treats most toys like a personal challenge. These Fuufome chew toys are the real deal. Right out of the box, you can tell they’re made from tough, high-quality nylon. My dog went to work on them immediately, and days later there’s barely any noticeable wear. No chunks missing, no sharp edges, and no mess on the floor. That alone puts these way above most toys I’ve tried. I also love that they actually keep my dog busy. Instead of getting bored and looking for something else to chew (like furniture), she’ll settle in and happily gnaw on these for a long time. It’s been great for mental stimulation and for redirecting destructive chewing. The fact that you get two durable toys in the pack is a bonus, and they’ve held up exactly as advertised. If you have a large breed or an aggressive chewer and you’re tired of wasting money on toys that don’t last, these are absolutely worth it. Highly recommend—this is one of the few chew toys that has truly lived up to the “indestructible” claim. 🐶💪

Happy hound!
Color: Yellow, Color: Yellow
My 2 yr old bloodhound destroys every toy in minutes, but not this one. My husband and I actually buy toys to see how long they last for fun. Although the croc is NOT indestructible, it lasts a whole lot longer than most. After an hr or so, I took away the only piece he's chewed off which is part of the back leg. Otherwise nothing else is missing off the croc. Our boy has been very occupied with this new toy and we're satisfied with his new distraction!

Definitely a tough toy
Color: Blue
This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.

Croc-sational
Color: Blue
My tough chewer is OBSESSED with Croc. Stands up well, small particles occasionally come off but this beats going thru 3 stuffies in an hour. Good value, easy to clean and great for our 91lb pitty
