The Guinea pig PCSK9 (Proprotein Convertase Subtilisin/Kexin Type 9) 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 PCSK9. 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 PCSK9 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 PCSK9, 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 PCSK9. You can calculate the concentration of Guinea pig PCSK9 in the samples by comparing the OD of the samples to the standard curve.

Durable Fun for Chew-Happy Dogs
Size: Medium, Style: Squeaker
This dog ball has been a hit with my dogs, despite their tendency to chew through toys. These balls hold up surprisingly well given his chewing habits, which is why I keep coming back to them. They provide endless fun with their squeaky feature, keeping my dogs engaged and active. One thing I really like is their durability. While my dogs do eventually chew them up, they last a significant amount of time compared to other toys we've tried. The squeaker adds an extra layer of excitement, making playtime even more enjoyable for my dog. However, if your dog is an aggressive chewer, be prepared for some wear, tear, and replacement over time. The squeaker balls are worth it for the durability and entertainment they provide with the current price tag. They withstand a good amount of chewing, making them a reliable choice for medium breeds that love to play and chew. Just remember that they will not last forever.

Squeaks for a while
Size: Medium, Style: Squeaker
I've got probably 10 of these, now. The squeaker fails pretty quickly. But our dog still likes them, just not as much as when they squeak. I'm tossing these a good 75 yards and farther. The Chuckit glowballs make sounds through their holes so no separate squeakers there. Dog really likes those glowballs.
