Description

Testing Principle:
This kit uses double antibody sandwich ELISA.Specific anti-human IL-11 capture antibody is prepackaged on a high affinity conjugate plate. The standard substance, the sample to be tested and the detection antibody labeled with biotin were successively added into the HRP-plate well. After full oscillation and mixing, the IL-11 in the sample was placed at room temperature for a 2-hour incubation process. The IL-11 in the sample was combined with the solid phase antibody and the detection antibody. After washing thoroughly to remove free and unbound ingredients, horseradish peroxidase labeled streptavidin-HRP (SA-HRP) is added. After washing again, TMB color substrate was added and incubated in dark at room temperature for color development. The depth of the color reaction was positively correlated with the concentration of IL-11 in the sample. The termination solution was added to terminate the reaction, and the absorbance value was measured at 450 nm detection wavelength (correction wavelength 570-630 nm) using a microplate analyzer.

Background:

Interleukin 11 (IL-11) is a pluripotent cytokine that was isolated from bone marrow mesenchymal stem cells as early as 1990. It is a member of the IL-6 cytokine family and can be distinguished according to the co-receptor they use, gp130. IL-11 plays an important regulatory role in hematopoietic regulation, especially in stimulating the maturation of megakaryocytes. Studies have shown that IL-11 can improve chemotherapy-induced laminopenia, induce acute phase protein, regulate antigen-antibody response, and participate in the regulation of proliferation and differentiation of bone cells. IL-11 causes bone resorption and also stimulates the growth of certain lymphocytes and, in a mouse model, increases the thickness and strength of the long bone cortex. As a signaling molecule, IL-11 has a variety of functions, including placental formation and to some extent decidualization, and plays a role in the implantation of blastocysts into the endometrium. IL-11, which is made using recombinant DNA technology and is marketed as Oprexil interleukin, is used to prevent severe thrombocytopenia in cancer patients.

Almost as good a chewing on my belt.
Size: 25 Inch
My corgi has always loved chasing her leash or a belt so I thought the snake would be a good fit for her. It quickly became her favorite. The squeakers lasted for maybe a month? Once there was a hole then we took them all out so she wouldn't choke. The snake without the squeakers is still a favorite. She's been chewing the tail end consistently and likes to lick it for some reason. I recommend this as a good tug toy. I like that it was made of leather.

DISAPPOINTED
Size: 25 Inch, Size: 25 Inch
I've bought this 9 times since it's my Maltipoos' favorite toy! Unfortunately the one that just came in is not up to par as those previously bought. The leather was cut sloppily & the sewing sometimes ran off the leather completely or so close to edges could easily be chewed open. I can't send back because bought as a treat before leaving for trip & the fact he's already seen it ! I used sewing machine to sew areas that were close to edges - had to take out stitches to remove top squeaker to be able to sew around that area on both sides. Don't know how long this one will last even though I used quilting thread which is a bit stronger than regular thread. Hope this was just a bad one & if so, wish company's quality control would have caught this & rejected it.

Not for aggressive chewers
Size: 36 Inch
My GSD ate half of it within 20min before I caught her. I don’t think it was meant for aggressive chewers so I can’t fault the product for that. My dogs did have a few hours of fun with it playing tug and it held up well.

Emotional Support Lizard
Size: 15 Inch
This was my Goldendoodle puppy's first toy, and a year later, it's still his favorite. It was light enough for him to play with it at 9 pounds, but big enough that he still loves it at 40 pounds. He carries it around, slaps his brother with it, throws it and chases it, sleeps with it, etc. He enjoys his stuffies also, but he returns to this one repeatedly through the day, so I know he loves it. It's a bit discolored, but still fully intact. If you have a dog with a soft mouth who isn't prone to chewing, this toy is perfect. I've purchased extras to keep in the emergency supplies in both the house and the car.
