This kit uses double antibody sandwich ELISA technology. Specific anti rat tnf-α Capture antibody was pre coated on a high affinity microplate. Add the standard and the sample to be tested 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 tnf-&alpha in the sample; Binding to solid-phase antibodies. After thorough washing to remove free and unbound components, biotinylated detection antibody was added for incubation.

Background:

Tumor necrosis factor alpha; (tnf-α)Also known as cachexia and tnfsf1a, it is an adipokine that participates in systemic inflammation and is also one of the cytokines that stimulate the acute phase response. It is mainly produced by activated macrophages, but also secreted by other types of cells, such as cd4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils and neurons. It has a variety of regulatory functions in the immune response and can also serve as a potential pyrogen. Tnf-α After responding to stimuli (infectious agents or tissue damage), it activates neutrophils in the systemic circulation, changes the characteristics of vascular endothelial cells, regulates the metabolic activity of other tissues, and exhibits tumor killing activity by inducing local coagulation. Tnf-α It plays an important role in the pathogenesis of inflammation in joint tissues and other tissues. Recently, more and more information shows that tnf-α It is also involved in the pathogenesis of AIDS. Tnf-α The assay is also very useful for transplantation research.

Wow
Scent: Peach, Size: 30.6 Fl Oz (Pack of 1)
This body wash smells amazing—light, fresh, and slightly sweet without being overwhelming. The white peach scent feels clean and relaxing, almost like a subtle spa vibe. It lathers well and leaves my skin feeling soft, smooth, and hydrated, not dry or tight. I also love that the scent lingers just enough after showering. Definitely a great everyday body wash if you want something gentle, moisturizing, and beautifully scented. Would repurchase!

Nice gentle body wash
Scent: Pomegranate & Hibiscus, Size: 30.6 Fl Oz (Pack of 1)
Love the shampoo it lathers on nicely and smells wonderful for the price it's fantastic. Hard to go wrong with a classic brand like Dove. I personally don't get the 24hr lotion support however. My skin still feels fairly dry by morning after taking a shower a night. Might be another cause but this hasn't seemed to help much. At very least however it leaves me feeling cleaning and smelling nice for the night.
