Anti-PDK1/PDHK1 Rabbit Polyclonal Antibody for WB, IF/ICC, ELISA - Q15118

Core Product Specifications and Parameters

Biological Background: PDK1/PDHK1 Function and Localization

• PDK1 (pyruvate dehydrogenase kinase isozyme 1) is a mitochondrial kinase that phosphorylates the pyruvate dehydrogenase subunits PDHA1 and PDHA2, playing a key role in the regulation of glucose and fatty acid metabolism and homeostasis. Related references: PMID:7499431, PMID:18541534, PMID:22195962

• By inhibiting pyruvate dehydrogenase activity, PDK1 down-regulates aerobic respiration, suppresses the formation of acetyl-coenzyme A from pyruvate, and regulates metabolite flux through the tricarboxylic acid cycle. Related references: PMID:18541534, PMID:22195962, PMID:26942675

• PDK1 plays an important role in cellular responses to hypoxia and is required for cell proliferation under low oxygen conditions, thereby helping cells adapt and survive in hypoxic environments. Related references: PMID:18541534, PMID:22195962, PMID:26942675

• The protein is localized to the mitochondrial matrix, positioning it in close proximity to its substrate, the pyruvate dehydrogenase complex, for rapid regulatory control.

• Tissue specificity: PDK1 is predominantly expressed in the heart, with lower levels detected in liver, skeletal muscle, and pancreas, consistent with its role in tissues with high metabolic demand.

• PDK1 is a phosphoprotein and undergoes alternative splicing, suggesting additional layers of functional regulation and isoform diversity.

Experimental Guidance and Technical Tips

• The immunogen corresponds to a C‑terminal region (amino acids 337‑436) of human PDK1, which is likely conserved across isoforms. Consider this design when evaluating isoform specificity in your experimental system.
• For Western blotting, the predicted molecular weight is ~49 kDa. Ensure thorough cell lysis and denaturation to release mitochondrial proteins; consider using RIPA buffer or enriched mitochondrial lysates to improve detection.
• In IF/ICC applications, co‑stain with mitochondrial markers (e.g., MitoTracker or COX IV antibody) to confirm the expected localization of PDK1 signal.
• For ELISA, optimize coating and detection conditions using a recombinant PDK1 protein standard, and validate linearity and sensitivity in your sample matrix.
• When working with mouse or rat tissues, remember that species‑specific sequence differences might affect antibody affinity; verify performance in each new system with appropriate positive and negative controls.
