Application

G-quadruplexes are four-stranded structures consisting of stacked G tetrads (G4) formed within select guanine-rich nucleic acid sequences. G-quadruplexes are enriched in open chromatin regions but are also present in the nucleolus and cytoplasm. The formation of G4 structures is dynamic and cell-type specific, suggesting interaction with transcription factors and other proteins. G-quadruplexes have therefore attracted acute interest in their possible contribution in transcriptional regulation.

MultiTASQ was designed utilizing the template-assembled synthetic G-quartets (TASQ) concept as biomimetic ligand for G-quadruplexes, demonstrating high specificity for G4. MultiTASQ is water-soluble and exhibits a high degree of intracellular accessibility. MultiTASQ detects ribosomal RNA-G4 associated with perinuclear rough ER regions to a greater degree compared to BG4 antibody. MultiTASQ is an alkynylated probe that allows for background-free detection via click chemistry and is suitable for G4 capture chemi-precipitation and click imaging applications.
