GSK 4027 is a PCAF GCN5 bromodomain chemical probe. In a time-resolved fluorescence resonanceenergytransfer (TR-FRET) assay, it has a pIC50 of 7.4±0.11 for PCAF.
DiIC1(5) is a signal-off fluorescent probe for the detection of mitochondrial membrane potential disruption. It accumulates in mitochondria and its fluorescence intensity decreases when the mitochondrial membrane potential is disrupted. DilC1(5) has been used in combination with a variety of cell damage and cell death markers to classify nine stages of cell death using flow cytometry. It has also been used as a quencher for the detection of serine phosphorylation and tyrosine dephosphorylation post-translational modifications (PTMs) in quenching resonanceenergytransfer (QRET) and mTR-FRET applications. It displays excitation emission maxima of 659 666 nm, respectively.
Sulforhodamine 101 DHPE, a fluorescent probe, results from the conjugation of sulforhodamine 101, a red fluorescent dye with excitation emission spectra of 586 605 nm, to the phospholipid 1,2-dipalmitoyl-sn-glycero-3-PE. It effectively integrates into phospholipid bilayers and is utilized for imaging solid supported lipid bilayers, detecting protein-ligand interactions on bilayers, and monitoring lipid probe colocalization in liposomes through resonanceenergytransfer (RET).
