This blocking peptide can be used as a control to neutralize Halorhodopsin before immunolocalization or western blot. Furter details are provided below.Halorhodopsin (HR) is a hyperpolarizing light-driven ion pump from the halophilic archaea bacterium Natronomonas pharaonis. HR uses the energy of yellow light (excitation maximum near 580 nm) to mediate primarily chloride but also bromide, iodide, and nitrate import into the cell against their electrochemical gradients.
Store at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.
