Product Specification

Description

Detection Principle:

This kit uses double antibody sandwich ELISA technology. The specific anti-human IL-9 capture antibody was pre coated on a high affinity microplate. Add the standard, the sample to be tested and the biotin labeled detection antibody into the wells of the enzyme plate in turn, shake well and mix well, and then place it at room temperature for 2 hours of incubation process. The IL-9 in the sample combines with the solid-phase antibody and the detection antibody. After washing sufficiently to remove free and unbound components, streptavidin HRP (sa-hrp) labeled with horseradish peroxidase was added. After washing again, TMB chromogenic substrate was added and incubated at room temperature in the dark to develop color. The depth of color response is positively correlated with the concentration of IL-9 in the sample. Add stop solution to stop the reaction, and use a microplate reader to measure the absorbance value at 450 nm detection wavelength (correction wavelength 570-630 nm).

Background:

Interleukin 9 (IL-9)It is a glycosylated protein with a molecular weight of 14kda and contains 10 cysteine residues involved in disulfide bonding. It is a cytokine produced by T cells, especially cd4+ helper cells, and can regulate a variety of hematopoietic cells. This cytokine stimulates cell proliferation and prevents apoptosis. It acts by binding to the IL-9 receptor and can activate different signal transduction and activation (STAT) proteins, thus participating in a variety of biological processes. The gene encoding this cytokine has been identified as a candidate gene for asthma. Genetic studies of asthma in mouse models have shown that this cytokine is a decisive factor in the pathogenesis of bronchial hyperresponsiveness. The presence of IL-9-mediated autocrine loops implies the presence of some malignancies such as Hodgkin's disease. IL-9 is expressed by Lee Stokes cells, Hodgkin lymphoma cells and some large aplastic lymphoma cells, but not by non Hodgkin lymphoma and peripheral T-cell lymphoma.

The perfect throw-on athletic dress (with built-in shorts!)
Size: Small, Color: Navy Blue
I’ve been loving this athletic dress—it’s one of those pieces that’s both functional and cute, which is hard to find. The fabric is lightweight, breathable, and slightly stretchy, so it’s comfortable whether you’re running errands, going for a walk, or just chasing kids around all day. The built-in shorts are a huge plus. They stay in place well and make it feel more secure than a regular dress, especially on busy days. I also appreciate the pockets—they’re actually usable and don’t feel bulky. The fit is relaxed and flowy, which I personally like because it’s easy and flattering without clinging. The straps are adjustable, so you can customize the fit a bit depending on your height or preference. I’d say it runs true to size for a looser fit. If you want it more fitted, you could size down, but I like the casual, sporty look as is. Overall, this is a great everyday summer staple—super easy to style with sneakers or sandals, and perfect for travel or on-the-go days. I’ll definitely be getting more colors!

Perfect for summer days.
Size: Medium, Color: Deep Gray, Size: Medium, Color: Deep Gray
I absolutely love this little athletic summer dress. I typically wear a size ten and ordered this in a medium and it's a perfect fit. I have the straps short so way it doesn't look baggy. It is super soft and comfortable. It is breathable and a perfect cut and length for me so so I plan on wearing it all during hot summer days. This is very versatile and easy to style by layering different things underneath it. I have a gray and leopard sports bra that is a really close shade of gray so it almost looks like it's one piece. I plan to order the teal as I have a swimsuit top that will match that color spot on. It seems like it is good quality and should hold up well to normal usage. I like that it has really big pockets , but I likely will not use them often lol. I just like the fact that if I need to have pockets they are there.
