(DB-410510)
AF 555 is a bright yellow-fluorescent dye that is structurally identical to Alexa Fluor 555. With its high photostability and pH resistance, it has become one of the most widely used fluorophores in life sciences.
The attached maleimide makes it a thiol-reactive dye for labeling of protein SH groups, and it can be used to attach AF 555 fluorophore to proteins and peptides containing cysteine residues, as well as to other thiolated molecules (such as thiol-containing oligonucleotides).
Package size
Key Parameters: Great brightness and pH stability with lower costs
Maleimide: Attaching AF 555to proteins with cystein residues or other thiolated molecules
Applications: Confocal Microscopy, Super Resolution Microscopy, Flow Cytometry (FACS), cell cultures and tissue labeling
Lower Cost Alternative: Same Spectral Properties & Performance – Works exactly like Alexa Fluor 555 with friendly price.
Complete Compatibility – Can be used in any existing protocol that uses Alexa Fluor 555
