Then a biotinylated detection antibody specific for Chicken GTF2F1 and Avidin Horseradish Peroxidase (HRP) conjugate

The Chicken GTF2F1 (General Transcription Factor IIF, 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 Chicken GTF2F1. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Chicken GTF2F1 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 Chicken GTF2F1, 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 Chicken GTF2F1. You can calculate the concentration of Chicken GTF2F1 in the samples by comparing the OD of the samples to the standard curve.

Beloved But Beware Microplastic Chip-Offs
Color: Bacon
My doodle adores this thing and gnaws on it constantly. He has not been able to harm it, which is great. That’s the best part. Things to be aware of: 1. This is mostly molded plastic; it is a bit heavy and very hard. My dog tosses it into the air and if it lands on him, it HURTS. A lot. 2. While it’s sturdy, sharp teeth eventually gnaw pieces and little shavings off the toy. These are microplastics and could be harmful if your dog swallows them.

Well-made and great size for the price!
Color: blue black
Very tough product, no odor of plastic, good toy for outside, perfect for medium or large dogs. Noise isn't too bad and the color is cute as well. Can't destroy this toy!

Durable Great for aggressive chewers
Color: Blue
Will make one whole room smell like fake bacon, but my dogs love it and it’s super strong and durable. I have a lab mixed with rotty and a full lab so it’s a perfect match.

Durable, Dogs love it
Color: Red
My Frenchie is a crazy chewer and can chew up a nylabone in a day, so I was looking for something that would last longer. So far this is holding up, and is pretty durable. Both my dogs like it a lot, it’s easy for them to grasp, and chewable but still very tough material. I suspect at some point it’ll wear down, but not for a while. The size was just as described / expected. Not too small and not too big
