Sample type: Tissue homogenate(lung tissue)

Sample species: Rat

Review: MSCs-HO-1 decreased LPS-mediated tumor necrosis factor α (TNF-α; a) and interleukin 1β (IL-1β; b) in sera of all groups at the indicated time points. (c, d) MSCs-HO-1 decreased LPS-induced TNF-α (c) and IL-1β (d) in the lungs of all groups at the indicated time points. All data are expressed as mean ± SEM (n = 6). *p < 0.05 versus 0 day time point, and #p < 0.05 versus lenti-HO-1-GFP and MSC groups at each time point.

Sample type: Serum

Sample species: Rat

Review: Effect of GABARAP and DCs on cartilage appearance and the expression of inflammatory cytokines in serum. In vivo cartilagerepair at 4 and 8 weeks postsurgery, (a) Macroscopic appearance and (b) macroscopic scores of femoral condyles were detected. Meanwhile, serum levels of (c) IL-6, (d) TNF-α, and (e) MMP-13 were determined using ELISA kits. Values are the means ± SD (n = 12). Bars with different letters are significantly different from each other at p < 0.05 and those with the same letter exhibit no significant difference. DC: differentiated chondrocytes; ELISA: enzyme-linked immunosorbent assay; GABARAP: γ-aminobutyric acid receptor-associated protein; SD: standard deviation 9Color figure can be viewed at wileyonlinelibrary.com).

 Q&A
Q:

Seeking for ELISA kits of TNF a .I am working on SD Rats and project related to High Fat Diet induced Metabolic complications.

A:
Thanks for your inquiry.
For the mentiond detection targets,we have the following kit:
#CSB-E11987r,Rat TNF-α ELISA kit
And we use kits to test ordinary rats.While there is not big problems to detect SD Rats.Pls take your actual test results as the real results
Q:

Rat TNF-α ELISA kit -CSB-E11987r this kit can be used for estimation in BALF...fluid
Kindly answer me.

A:
Thanks for your enquiry.
We usually use this kit to test serum, plasma, cell culture supernates, tissue homogenates.If you want to test bronchoalveolar lavage fluid,we suggest you do pre-testing first.If the content of your sample falls in the detection range,it can usually be detected out.
The manual will be provided to you by e-mail.
Pls let me know if you have any further questions. Thank you.
Q:

I want to know what the normal serum concentrations of TNFa in experimental rats are and the serum concentrations of TNFa in an induced freund adjuvant RA in experimental rats during 7 weeks. And I want to know the concentrations estimated in nano gramml. I want to ask about the weight loss of experimental animal rats also during an induced freund adjuvant arthritis RA during 7 weeks estimated by the gram.

A:

We used this CSB-E11987r Rat TNF-α ELISA kit to measure normal serum/plasma samples on rats. The model with heavy inflammation could even reach hundreds of pg/ml. The results varied with different conditions of the sample and different organism models. As to the mentioned induced model, we are not so sure about the sample condition. We suggest taking the actual measurement as your real result.
As to your question about weight loss, it usually depends on your own experiment aim or the choice of your target. If you just want to test TNF-α, then it is just ok to use the form of concentration of TNF-α.

Target Background

Function
(From Uniprot)
Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation. Induces insulin resistance in adipocytes via inhibition of insulin-induced IRS1 tyrosine phosphorylation and insulin-induced glucose uptake. Induces GKAP42 protein degradation in adipocytes which is partially responsible for TNF-induced insulin resistance. Plays a role in angiogenesis by inducing VEGF production synergistically with IL1B and IL6.; The TNF intracellular domain (ICD) form induces IL12 production in dendritic cells.
