Hello,

I would recommend using an antibody database available at Labome.com. Regarding the voltage gated sodium channel antibodies, you can start with the following link: http://www.labome.com/bin/ea.pl?q=sodium+channel, where you can find additional links to the antibodies to different subunits of voltage gated sodium channel and references. For example, for sodium channel protein type I subunit alpha (Nav1.1) you can check this link: http://www.labome.com/review/gene/human/SCN1A-antibody.html. For Nav1.1 subunit, Sigma Aldrich has mouse monoclonal antibody S8809, which can be used for both IHC (reference: Dumas et al., Glia 2015) and WB. I hope this comment is helpful.

Thank you Konstantin Yakimchuk for your reply, will look it up. 

Alomone Labs is something of a specialist in sodium and potassium channels. Here is our current listing of some of their Nav Abs:
