The NFIB gene is a part of the NFI gene complex that includes three other genes (NFIA, NFIC and NFIX). The NFIB gene is a protein coding gene that also serves as a transcription factor. This gene is essential in embryonic development and it works together with its gene complex to initiate tissue differentiation in the fetus. Through knockout experiments, researchers found that mice without the NFIB gene have severely underdeveloped lungs. This mutation does not seem to cause spontaneous abortions because in utero the fetus does not use its lungs for respiration. However, this becomes lethal once the fetus is born and has to take its first breath. It is thought that NFIB plays a role in down regulating the transcription factors TGF-?1 and Shh in normal gestation because they remained high in knockout experiments. The absence of NFIB also leads to insufficient amounts of surfactant being produced which is one reason why the mice cannot breathe once it is born. The knockout experiments demonstrated that NFIB has a significant role in fore-brain development. NFIB is typically found in pontine nuclei of the CNS, the cerebral cortex and the white matter of the brain and without NFIB these areas are dramatically affected.\u003c\/p\u003e\u003cp\u003eThis anti-NFIB antibody is supplied as Purified (Mouse, Monoclonal (mouse origin), clone 4D6E4, Mouse IgG2b, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.\u003c\/p\u003e\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget:\u003c\/strong\u003e NFIB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Purified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocalization:\u003c\/strong\u003e Nuclear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecies reactivity:\u003c\/strong\u003e Human, Mouse, Rat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications (listed):\u003c\/strong\u003e WB, IF, FACS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConjugate:\u003c\/strong\u003e Unconjugated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClone and antibody class:\u003c\/strong\u003e Monoclonal (mouse origin), clone 4D6E4, Mouse IgG2b\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.\u003c\/p\u003e\u003ch2\u003eBiological background\u003c\/h2\u003e\u003cp\u003eNFIB is referenced in public gene\/protein resources (e.g., UniProt and NCBI Gene), which provide curated names\/synonyms, protein features, and pathway context.
