Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
Shipping
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
NFKBIE, also known as IκBε (Inhibitor of Nuclear Factor kappa-B epsilon), is a member of the IκB family of proteins, which are crucial regulators of the NF-κB (Nuclear Factor kappa-light-chain-enhancer of activated B cells) signaling pathway. This pathway plays a vital role in controlling immune responses, inflammation, cell survival, and proliferation. Upon stimulation by various cytokines or stress signals, NF-κB dimers, typically composed of p65 (RelA) and p50, are released from their inhibitor complexes, allowing them to translocate to the nucleus and initiate the transcription of target genes involved in immune and inflammatory responses. NFKBIE specifically functions to inhibit the NF-κB pathway by sequestering NF-κB dimers in the cytoplasm and preventing their nuclear translocation. Elevated levels of NFKBIE have been associated with certain cancers and autoimmune diseases, indicating its potential as a therapeutic target. Understanding the functional dynamics of NFKBIE, including its expression regulation and interaction with other NF-κB components, is essential for developing novel therapeutic strategies aimed at modulating NF-κB activity. The production and study of recombinant NFKBIE protein can provide valuable insights into its structural properties, mechanism of action, and role in disease pathology, ultimately contributing to the development of targeted interventions in NF-κB-related disorders. Research exploring the biochemical and biophysical characteristics of this protein may pave the way for innovative approaches in both basic and clinical research focused on immune modulation and inflammation control.
