PDE4B belongs to the type 4 phosphodiesterase family, which provides fine control of intracellular cAMP concentrations. The PDE4B antibody is used in research focused on inflammation, neuroscience, and psychiatric disorders involving cAMP signaling dysregulation.\u003cbr\u003e\u003cbr\u003ePDE4B is encoded by the PDE4B gene on human chromosome 1p31.3. The protein exists in multiple isoforms ranging from 70 to 100 kilodaltons, all containing a catalytic domain, upstream conserved regions (UCR1 and UCR2), and regulatory sequences that determine localization and activation. PDE4B localizes to cytoplasmic and perinuclear regions and interacts with signaling complexes via A-kinase anchoring proteins (AKAPs).\u003cbr\u003e\u003cbr\u003eThe PDE4B antibody identifies characteristic isoforms in western blot. Functionally, PDE4B hydrolyzes cAMP generated by G protein-coupled receptor activation, shaping responses to neurotransmitters, hormones, and immune stimuli. It regulates protein kinase A (PKA) activity and downstream transcription factors such as CREB.\u003cbr\u003e\u003cbr\u003eIn immune cells, PDE4B modulates cytokine production and inflammatory responses. Inhibition of PDE4B enhances cAMP signaling, reducing pro-inflammatory cytokines like TNF-alpha and IL-6. In the central nervous system, PDE4B regulates neuronal excitability, memory, and emotional processing. Genetic and pharmacologic studies implicate PDE4B dysfunction in depression, schizophrenia, and addiction.\u003cbr\u003e\u003cbr\u003ePDE4B is a therapeutic target for anti-inflammatory and neuropsychiatric drugs. Selective inhibitors such as rolipram and roflumilast have been developed to modulate cAMP signaling.\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=PDE4B - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=PDE4B - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=PDE4B - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/PDE4B - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=PDE4B+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047290888557,"sku":"FY12523","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_0d154219-890a-4957-adce-b6eaa95f1f4c.jpg?v=1782237004","url":"https:\/\/www.ebiohippo.com\/products\/pde4b-antibody-phosphodiesterase-4b-bha17135426","provider":"BioHippo","version":"1.0","type":"link"}
