TRAM 34 worked ideally as a channel blocker on different cell lines
By Sadequl Islam on 10/13/2018
Species: Human

Product used for understanding blocking mechanism of calcium activated potassium channel. Product must be dissolved in DMSO, on mild heat. Shows great potential for research in KCa channel studies.
