BL 1249 performed ideally on biology lab conditions.

Great potassium channel activator. Was studied on potassium channel expressed on human brain cells. The product performed well under experimental conditions and would purchase again.

The product dissolved in DMSO must be handled carefully as it easily crosses cell membrane.
