Co-immunoprecipitation of Nav1.5 and TRPM4 in HEK-293 cells. (A) Left panel: Input signals confirming the expression of Nav1.5 with or without FLAG tag and TRPM4. The alpha subunit of the Na/K pump was used as a loading control. Right panel: In the immunoprecipitated (IP) fraction, the signal was observed only in the presence of FLAG-Nav1.5 and TRPM4. (B) Left panel: Input signals confirming the expression of Nav1.5 with or without FLAG tag and TRPM5. Right panel: In the immunoprecipitated fraction, no signal was observed for TRPM5, even though the IP of FLAG-Nav1.5 was successful.
