Structure
Molecular formula C210H316N62O61S6
Activity Anthopleurin-C is a potent cardiotoxin, which evokes a positive inotropic and chronotropic effect on mammalian heart muscle1,2. It also modifies the current passing through the fast Na+ channel in neuroblastoma cells, leading to delay and incomplete inactivation2.
Accession number P01532
Shipping and storage Shipped at room temperature. Product as supplied can be stored intact at room temperature for several weeks. For longer periods, it should be stored at -20°C. Protect from light and moisture.
Solubility Soluble in DDW.
Centrifuge all products before use (10000 x, g 5 min). Avoid multiple freezing and thawing. It is recommended to prepare fresh solutions in working buffers before use, or aliquot stock solutions reconstituted in distilled water and keep at -20°C. Upon use, dilute the stock solution in the desired working buffer.
