Custom Premix Selecting "Custom Premix" option means that all of the beads you have chosen will be premixed in manufacturing before the kit is sent to you.
A potent blocker of hyperpolarization-activated cyclic nucleotide-gated channels (HCN channels) in heart and brain tissue. Recently shown to also block Na(+) currents in DRG neurons and in HEK293 cells transfected with Na(v)1.4 plasmids. In voltage clamp experiments, it is shown to reduce Ih in a time- and concentration-dependent manner (IC50 = 2 mM). Suggested to behave as a lipophilic quaternary cation that can pass into the cell interior to block Ih channels in their closed state.
Please note that the molecular weight for this compound is batch-specific due to variable water content.
