Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of mouse NF-κB in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

The mouse NF-κB ELISA Kit is engineered for accurate measurement of mouse NF-κB levels from samples including serum, plasma, or tissue homogenates. It uses the Sandwich-ELISA mechanism in combination with the enzyme-substrate chromogenic reaction to measure the NF-κB content in the sample. The color intensity is positively correlated with NF-κB content in the sample. This kit has been validated against standards of sensitivity, specificity, precision, linearity, recovery, and lot-to-lot consistency.

NF-κB is a central mediator of inflammation with multiple links to thrombotic processes. It is involved in the regulation of expression of various genes encoding cytokine, chemokines, adhesion molecules, and anti-microbial peptides, thus orchestrating both innate and adaptive immune responses. Additionally, NF-κB plays a crucial role in modulating the survival, activation, and differentiation of innate immune cells and inflammatory T cells. It targets inflammation not only by boosting the synthesis of inflammatory molecules but also by regulating cell proliferation, apoptosis, morphogenesis, and differentiation. Abnormal NF-κB activation leads to aberrant T cell activation, which is related to autoimmune and inflammatory responses.

I want to ask about sample processing of CSB-E12108m, Mouse Nuclear factor-kappa B, NF-κB ELISA Kit. I have a serum sample but before using it for the ELISA test I will treat it at a temperature of 56℃ for 30min for heat deactivation, would it affect the cytokine which I want to detect? What will be the sensitivity if my samples are preheated?


Generally speaking, the high temperature would denature the protein and affect the detection result. The mentioned treatment with a temperature of 56℃ for 30min is usually used in the inactivation. There should be not much effect to do so. However, our ELISA kit does not require extra special steps or operations. As to the serum preparation, we suggest you follow the manual.

Target Background

(From Uniprot)
NF-kappa-B is a pleiotropic transcription factor present in almost all cell types and is the endpoint of a series of signal transduction events that are initiated by a vast array of stimuli related to many biological processes such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52 and the heterodimeric p65-p50 complex appears to be most abundant one. The dimers bind at kappa-B sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappa-B sites that they can bind with distinguishable affinity and specificity. Different dimer combinations act as transcriptional activators or repressors, respectively. NF-kappa-B is controlled by various mechanisms of post-translational modification and subcellular compartmentalization as well as by interactions with other cofactors or corepressors. NF-kappa-B complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappa-B inhibitor (I-kappa-B) family. In a conventional activation pathway, I-kappa-B is phosphorylated by I-kappa-B kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kappa-B complex which translocates to the nucleus. NF-kappa-B heterodimeric p65-p50 and RelB-p50 complexes are transcriptional activators. The NF-kappa-B p50-p50 homodimer is a transcriptional repressor, but can act as a transcriptional activator when associated with BCL3. NFKB1 appears to have dual functions such as cytoplasmic retention of attached NF-kappa-B proteins by p105 and generation of p50 by a cotranslational processing. The proteasome-mediated process ensures the production of both p50 and p105 and preserves their independent function, although processing of NFKB1/p105 also appears to occur post-translationally. p50 binds to the kappa-B consensus sequence 5'-GGRNNYYCC-3', located in the enhancer region of genes involved in immune response and acute phase reactions. Plays a role in the regulation of apoptosis. Isoform 5, isoform 6 and isoform 7 act as inhibitors of transactivation of p50 NF-kappa-B subunit, probably by sequestering it in the cytoplasm. Isoform 3 (p98) (but not p84 or p105) acts as a transactivator of NF-kappa-B-regulated gene expression. In a complex with MAP3K8, NFKB1/p105 represses MAP3K8-induced MAPK signaling; active MAP3K8 is released by proteasome-dependent degradation of NFKB1/p105.
