Application

  • Abberior® CAGE 552 has been conjugated with secondary anti-guinea pig antibody for PALM (photo-activated light microscopy) imaging in MDA-MB-468 and COS-7 cells.
  • It has been labelled with secondary antibody to perform dSTORM (direct stochastical optical reconstruction microscopy) for localization of deposited callose in destained Arabidopsis thaliana leaves.
  • Abberior® CAGE 552 goat anti-mouse antibody has been used for FPALM (fluorescence photoactivation localization microscopy) imaging in NIH-3T3 fixed cells.
  • It has been used for PALM imaging of silica colloids.
  • It has also been used for PALM imaging of functionally asymmetric GPCR (G protein-coupled receptor) oligomers.

The introduction of super-resolution fluorescence microscopy (SRM) opened an unprecedented vista into nanoscopic length scales, unveiling a new degree of complexity in biological systems in aqueous environments. Regrettably, supramolecular chemistry and material science benefited far less from these recent developments.

Formation of G protein-coupled receptors (GPCRs) into dimers and higher order oligomers represents a key mechanism in pleiotropic signaling, yet how individual protomers function within oligomers remains poorly understood. We present a super-resolution imaging approach, resolving single GPCR molecules to

Ethanol affects the signaling of several important neurotransmitter and neuromodulator systems in the CNS. It has been recently proposed that ethanol alters the dynamic lateral organization of proteins and lipids in the plasma membrane, thereby affecting surface receptor-mediated cellular signaling.

Localization microscopy can image nanoscale cellular details. To address biological questions, the ability to distinguish multiple molecular species simultaneously is invaluable. Here, we present a new version of fluorescence photoactivation localization microscopy (FPALM) which detects the emission spectrum of each

Successful defence of plants against colonisation by fungal pathogens depends on the ability to prevent initial penetration of the plant cell wall. Here we report that the pathogen-induced (1,3)-β-glucan cell wall polymer callose, which is deposited at sites of attempted
