NF-κB p105/p50 is the class 1 member of the nuclear factor of kappa light polypeptide gene enhancer in B-cells (NF-κB) transcription factor family. NFKB1 is synthesized as a longer precursor protein, p105, which can be prolytically processed into shorter proteins, p50 and IκBγ. Both p105 and IκBγ proteins contain IκB-like ankyrin repeats that can act as NF-κB inhibitors. P50 protein forms active DNA-binding heterodimers with RelA/NF-κB p65 and c-REL. Stimulation by inflammatory signals, such as TNFα, IL-1, and LPS, lead to the proteosomal degradation of IκBα and result in the translocation of RelA/NF-κB p65:p50 and c-Rel:p50 heterodimers to the nucleus. Subsequently, the nuclear NF-κB subunits bind to target genes and regulate gene transcription. NFKB1 is a key component of the NF-κB signaling pathway and is involved in the regulation of various biological processes including cell proliferation, differentiation, apoptosis, and immune responses.Product Details

WB - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 1:500-1:5000 diluted (0.1 – 1 µg/mL). It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
The clone W16200A detects both p105 precursor protein and p50 subunit.
As per the Human Protein Atlas RNA level dataset, Molt-4 cell is expected to have a low level of NF-κB p105/p50 expression.
This clone does not work for IF microscopy application (in-house tested).
This clone is not recommended for ChIP (Chromatin Immunoprecipitation) assays (as determined by in-house testing).
