Description

Human COL11Alpha1 (Collagen Type Ⅺ Alpha 1) ELISA KitThe Human COL11Alpha1 (Collagen Type Alpha 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 Human COL11Alpha1. 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 COL11Alpha1 and Avidin Horseradish Peroxidase (HRP) conjugate are added

The Human COL11Alpha1 (Collagen Type Ⅺ Alpha 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 Human COL11Alpha1. 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 COL11Alpha1 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 COL11Alpha1, 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 COL11Alpha1. You can calculate the concentration of Human COL11Alpha1 in the samples by comparing the OD of the samples to the standard curve.

Safe and fun chew toy
Color: All, Number of Items: 12, Color: All, Number of Items: 12
My dog loves this straw toy immediately. It keeps her entertained and the natural materials are safe and easy to clean. Yes, she tears it up but that’s the part of the fun. I will keep buying.

Nice Idea, but Durability Was Very Limited
Color: Reed, Seaweed & Corn Husk, Seaweed & Corn Silk, Number of Items: 3
These woven grass chew balls are a nice concept and made from natural materials, which I appreciated. They are lightweight, easy for dogs to carry, and can be fun for light play or supervised interaction. The texture also seems appealing for chewing and tossing around. However, the main issue was durability. For my miniature Goldendoodle, the toys lasted only a few minutes before starting to come apart. If your dog is an active chewer, these may not hold up very long. They may be better suited for very gentle chewers or short-term play rather than dogs that like to really chew. The natural material aspect is a plus, but longevity was disappointing. Because of the limited durability, I’m giving these three stars. Good idea, but they did not last long enough for my dog.

Fun outdoor/indoor mental stimulation for dogs
Color: All, Number of Items: 12
These Natural dog chew toys are great; here are a few highlights from my experience: • Woven by hand with 100% natural ingredients such as corn leaf, reed, timothy hay, corn husk corn silk, and seaweed. • These toys are lightweight and can be used as a chew toy, play toy, or for mental stimulation. These have a light sent to them, so I hid them around our large farm and let the pups search for them by scent. It was challenging for them, but they were so excited when they found them. • They are tied together like a puzzle rope. One of my pups loves the challenge of slowing trying to unravel this, while the other one just wants to destroy it. • I let my dogs have these outside only, that way if they are destroyed it will just be natural fertilizer for our farm. If you want them to use them inside, they may get messy depending on how aggressive a chewer your dog is. • Some of these will last longer than others just because they have different natural ingredients. Keep in mind that these are great, but they are not rubber, so they are not meant to last for years with a dog that is an aggressive chewer. • Depending on your dog and how they are, these may last for a long time, or for a short time. They will last for a while if your pup is a light chewer, but if they are an aggressive chewer they may not last very long. Either way you are giving your dog a natural fun toy that will challenge them while still keeping them healthy.

Did not work for my dog.

Never again will I get these. I got this for my heeler puppy and she demolished them within seconds and the pieces got stuck in her teeth. I also did some research and dogs should not eat corn husk do you own research but it’s not recommended.

Nice enrichment toy for active dogs
This is a fun interactive dog toy for days when my dog needs extra activity inside. The automatic rolling motion makes it more engaging than a standard ball. It works best on hard floors or flat surfaces, and the USB-C charging is convenient.
