    You are correct that BODIPY is in fact highly lipid soluble. Currently, as we do not carry out our own research for these products, we are unable to know if this compound is able to bind to intracellular receptors. As this range of compounds were d...

    These compounds are generally not cell-permeable and have been developed to bind to extracellular receptors. There might be a small amount of receptor internalisation but this is not the primary effect. If you are able to work out a way to transport...

    All of these fluorescent ligands are not suitable for use in paraffin embedded sections as non-specific binding will be seen. The best results are seen using live cells, as this will allow the ligand to bind t...
