[Atto655]-LifeAct (Abp140 1-17) contains the 17 amino acid peptide Lifeact derived from amino acids 1-17 of the Saccharomyces cerevisiae actin binding protein, Abp140. These first 17 amino acids of Abp140 are crucial in allowing Lifeact to localise to actin filaments (F-actin) and therefore it can be used as a cytoskeletal marker. One application of lifeact is in the study of plant development and pathogen defence as filamentous actin within the plant’s actin cytoskeleton is important in key processes such as cell division, membrane trafficking and stomatal movements. The addition of the oxazine fluorophore Atto655 which has single molecule (SM) imaging properties allows the location of the LifeAct (Abp140 1-17) to be detected.
