Description

Canine IL-12 p40 (Interleukin 12 p40) ELISA KitThe Canine IL 12 p40 (Interleukin 12 p40) 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 Canine IL 12 p40. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Canine IL 12 p40 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively

The Canine IL-12 p40 (Interleukin 12 p40) 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 Canine IL-12 p40. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Canine IL-12 p40 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 Canine IL-12 p40, 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 Canine IL-12 p40. You can calculate the concentration of Canine IL-12 p40 in the samples by comparing the OD of the samples to the standard curve.

Durable construction, including squeakers!
Style: Snake
This is the absolute best toy I've found. My dog is a 40 lb staffie who loves to play tug and chew. I'm used to toys lasting one day to one week and this one lasted about four months of almost constant daily play. The squeakers finally collapsed, so I'm buying my second one. I wish they would embroider the name of their brand on the toy because I forgot what the brand name was and it was hard to find again. Thankfully, I combed through my purchase records and finally found it. This brand definitely is my go-to for durable toys from now on!

Very nice, LOUD toy
Style: Crocodile
My parents' dog had the shark version of this toy already, and I looked to see if there were any other versions of the same toy. I found this crocodile. This thing is hysterical when he plays with it. I think each squeaker makes a slightly different sound, so you can hear him switch from 1 part to another. This is not for you if you like quiet. It is very loud but our dog doesn't like toys that don't squeak. The shark has held up for along time, and the crocodile is doing well so far. He's pretty rough on his toys, but he hasn't torn these or broken the squeakers. The fabric is soft, and it's well sewn. There's no stuffing in the body or limbs, so small holes don't really matter. It's big enough for larger dogs (ours is 45lb). The price was very good for a large toy that's high quality.

It's holding up better than I thought it would
Style: Snake
*EDIT* I originally gave this toy a 1 star rating. I changed that to a 4. Even though my dog immediately put holes in it, it's still holding up. She absolutely loves her Snakey, and takes it to bed with her. She hasn't even chewed the eyes off, like she would normally do. There's even still a piece of the tongue left lol! I gave this to my dog tonight. She's already torn a hole in the tail. I just found a hole next to a squeaker, and she's almost chewed the tongue off. This toy is not durable at all. I do not recommend this for any dog that likes to chew.
