Description

Human SPTBetaN4 (Spectrin Beta, Non Erythrocytic 4) ELISA KitThe Human SPTBetaN4 (Spectrin Beta, Non Erythrocytic 4) 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 Human SPTBetaN4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human SPTBetaN4 and Avidin Horseradish Peroxidase (HRP) conjugate are added

The Human SPTBetaN4 (Spectrin Beta, Non Erythrocytic 4) 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 Human SPTBetaN4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human SPTBetaN4 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 Human SPTBetaN4, 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 Human SPTBetaN4. You can calculate the concentration of Human SPTBetaN4 in the samples by comparing the OD of the samples to the standard curve.

Adorable but not Durable
Color: Blue
While this toy was super adorable and our 1 year old puppy loved it. The colors were bright and vivid, and it made fun wrinkling sounds he absolutely loved. However we were lucky if it lasted 20 minutes. Within minutes the crinkle paper was coming out and it basically fell apart, and he's not a destructive pup.

A Must-Have for Toy-Loving Pups!
My Frenchie is obsessed with this Pawatoga bottle toy! The design is adorable and such a fun twist, but what impressed me most is how durable it’s been. He’s been chewing, tossing, and carrying it around non-stop, and it’s still holding up perfectly. The plush exterior is soft enough for him to snuggle, but the construction is sturdy enough to survive his play sessions. Bonus points for how easy it is to clean and how cute it looks when he’s “sipping” from it! If your dog loves plush toys but you’re tired of them falling apart in a day, this one’s definitely worth it. Stylish, tough, and totally pup-approved.
