AM1-44 is a version of AM1-43 (catalog no. 70024) with improved fixability. The dye can also be used as a general probe for following endocytosis. AM1-44 probe functions similarly as AM1-43, except that AM1-44 has lipophilic tails that are each one carbon longer than those of AM1-43, resulting in better fixability.
