CL264 Rhodamine is provided as a pink lyophilized and shipped at room temperature. Store at -20°C. Upon resuspension, CL264 Rhodamine should be aliquoted and stored at -20°C. Lyophilized product is stable 1 year at -20°C when properly stored. Resuspended product is stable 6 months at -20°C. Avoid repeated freeze-thaw cycles.
CL264 is a novel 9-benzyl-8 hydroxyadenine derivative containing a glycine on the benzyl group (in para). Similarly to SM360320, CL264 induces the activation of NF-κB and the secretion of IFN-α in TLR7-expressing cells . CL264 is a TLR7-specific ligand, it does not stimulate TLR8 even at high concentrations (> 10 µg/ml). In TLR7-transfected HEK293 cells, CL264 triggers NF-κB activation at a concentration of 0.1 µM which is 5-10 times less than imiquimod. CL264 is labeled with Rhodamine on the acid group of the glycine via a HEX spacer. CL264 Rhodamine can be used confocal laser-scanning microscopy or flow cytometry.
